　等差数列是常见数列的一种，如果一个数列从第二项起，每一项与它的前一项的差等于同一个常数，这个数列就叫做等差数列。以下是我为您整理的关于2017年高考数学必考等差数列公式的相关资料，希望对您有所帮助。

　高中数学知识点：等差数列公式

　等差数列公式an=a1+(n-1)d

　a1为首项，an为第n项的通项公式，d为公差

　前n项和公式为：Sn=na1+n(n-1)d/2

　Sn=(a1+an)n/2

　若m+n=p+q则：存在am+an=ap+aq

　若m+n=2p则：am+an=2ap

　以上n.m.p.q均为正整数

　解析：第n项的值an=首项+(项数-1)?公差

　前n项的和Sn=首项?n+项数(项数-1)公差/2

　公差d=(an-a1)?(n-1)

　项数=(末项-首项)?公差+1

　数列为奇数项时，前n项的和=中间项?项数

　数列为偶数项，求首尾项相加，用它的和除以2

　等差中项公式2an+1=an+an+2其中{an}是等差数列

　通项公式：公差?项数+首项-公差

　高中数学知识点：等差数列求和公式

　若一个等差数列的首项为a1，末项为an那么该等差数列和表达式为：

　S=(a1+an)n?2

　即(首项+末项)?项数?2

　前n项和公式

　注意：n是正整数(相当于n个等差中项之和)

　等差数列前N项求和，实际就是梯形公式的妙用：

　上底为：a1首项，下底为a1+(n-1)d，高为n。

　即[a1+a1+(n-1)d]* n/2={a1n+n(n-1)d}/2。

　高中数学知识点：推理过程

　设首项为 , 末项为 , 项数为 , 公差为 , 前 项和为 , 则有:

　当d?0时，Sn是n的二次函数，(n，Sn)是二次函数 的图象上一群孤立的点。利用其几何意义可求前n项和Sn的最值。

　注意：公式一二三事实上是等价的，在公式一中不必要求公差等于一。

　求和推导

　证明：由题意得：

　Sn=a1+a2+a3+。。。+an①

　Sn=an+a(n-1)+a(n-2)+。。。+a1②

　①+②得：

　2Sn=[a1+an]+[a2+a(n-1)]+[a3+a(n-2)]+...+[a1+an](当n为偶数时)

　Sn={[a1+an]+[a2+a(n-1)]+[a3+a(n-2)]+...+[a1+an]}/2

　Sn=n(A1+An)/2 (a1，an，可以用a1+(n-1)d这种形式表示可以发现括号里面的数都是一个定值，即(A1+An)

　基本公式

　公式　Sn=(a1+an)n/2

　等差数列求和公式

　Sn=na1+n(n-1)d/2; (d为公差)

　Sn=An2+Bn; A=d/2,B=a1-(d/2)

　和为 Sn

　首项 a1

　末项 an

　公差d

　项数n

　表示方法

　等差数列基本公式:

　末项=首项+(项数-1)?公差

　项数=(末项-首项)?公差+1

　首项=末项-(项数-1)?公差

　和=(首项+末项)?项数?2

　差:首项+项数?(项数-1)?公差?2

　说明

　末项:最后一位数

　首项:第一位数

　项数:一共有几位数

　和:求一共数的总和

　本段通项公式

　首项=2?和?项数-末项

　末项=2?和?项数-首项

　末项=首项+(项数-1)?公差:a1+(n-1)d

　项数=(末项-首项)/ 公差+1 :n=(an-a1)/d+1

　公差= d=(an-a1)/n-1

　如：1+3+5+7+99 公差就是3-1

　将a1推广到am，则为:

　d=(an-am)/n-m

　基本性质

　若 m、n、p、q?N

　①若m+n=p+q，则am+an=ap+aq

　②若m+n=2q，则am+an=2aq(等差中项)

　We have designed all our bank cards to make your life easier.

　Using your NatWest Service Card

　As a Switch card, it lets you pay for all sorts of goods and services, whenever you see the Switch logo. The money comes straight out of your account, so you can spend as much as you like as long as you have enough money (or an agreed overdraft (透支) to cover it). It is also a cheque guarantee card for up to the amount shown on the card. And it gives you free access to your money from over 31,000 cash machines across the UK.

　Using your NatWest Cash Card

　You can use your Cash Card as a Solo card to pay for goods and services wherever you see the Solo logo. It can also give you access to your account and your cash from over 31,000 cash machines nationwide. You can spend or withdraw what you have in your account, or as much as your agreed overdraft limit.

　Using your cards abroad

　You can also use your Service Card and Cash Card when you?re abroad. You can withdraw cash at cash machines and pay for goods and services wherever you see the Cirrus or Maestro logo displayed.

　We take a commission charge (手续费) of 2.25% of each cash withdrawal you make (up to￡4) and a commission charge of 75 pence every time you use Maestro to pay for goods or services. We also apply a foreign-exchange transaction fee of 2.65%.

　Using your NatWest Credit Card

　* Pay for goods and services and enjoy up to 56 days? interest-free credit.

　* Pay in over 24 million shops worldwide that display the MasterCard or Visa logos.

　B. You can use the card in any shop across the world.

　C. You will be charged some interest beyond two months.

　D. You will gain one air mile if you spend ￡20 on traveller?s cheques.

　B

　Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I?ve ever had: Be bold and brave ? and mighty (强大的) forces will come to your aid.

　Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

　Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas ? even physical strength greater than most of us realize.

　Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. ?In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,? said Tim. ?I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet ? and stopped him cold.?

　Boldness ? a willingness to extend yourself to the extreme?is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

　So, always try to live a little bit beyond your abilities?and you?ll find your abilities are greater than you ever dreamed.

　25. Why was the author sometimes unable to reach his goal in the past?

　A. He faced huge risks. B. He lacked mighty forces.

　C. Fear prevented him from trying. D. Failure blocked his way to success.

　26. What is the implied meaning of the underlined part?

　A. Swallow more than you can digest. B. Act slightly above your abilities.

　C. Develop more mysterious powers. D. Learn to make creative decisions.

　27. What can be learned from Paragraph 5?

　A. Confidence grows more rapidly in adults. B. Trying without success is meaningless.

　C. Repeated failure creates a better life. D. Boldness can be gained little by little.

　C

　The wallet is heading for extinction. As a day-to-day essential, it will die off with the generation who read print newspapers. The kind of shopping-where you hand over notes and count out change in return?now happens only in the most minor of our retail encounters，like buying a bar of chocolate or a pint of milk from a corner shop. At the shops where you spend any real money, that money is increasingly abstracted. And this is more and more true, the higher up the scale you go. At the most cutting-edge retail stores?Victoria Beckham on Dover Street, for instance?you don't go and stand at any kind of cash register when you decide to pay. The staff are equipped with iPads to take your payment while you relax on a sofa.

　Which is nothing more or less than excellent service, if you have the money. But across society, the abstraction(抽象) of the idea of cash makes me uneasy. Maybe I'm just old-fashioned. But earning money isn't quick or easy for most of us. Isn't it a bit incredible that spending it should happen in half a blink(眨眼)of an eye? Doesn't a wallet?that time-honoured Friday-night feeling of pleasing, promising fatness?represent something that matters?

　But I'll leave the economics to the experts. What bothers me about the death of the wallet is the change it represents in our physical environment. Everything about the look and feel of a wallet?the way the fastenings and materials wear and tear and loosen with age, the plastic and paper and gold and silver, and handwritten phone numbers and printed cinema tickets?is the very opposite of what our world is becoming. The opposite of a wallet is a smartphone or an iPad. The rounded edges, cool glass, smooth and unknowable as pebble(鹅卵石). Instead of digging through pieces of paper and peering into corners, we move our fingers left and right. No more counting out coins. Show your wallet, if you still have one. It may not be here much longer.

　28. What is happening to the wallet?

　A. It is disappearing. B. It is being fattened.

　C. It is becoming costly. D. It is changing in style.

　29. What makes the author feel uncomfortable nowadays?

　A. Saving money is becoming a thing of the past.

　B. The pleasing Friday-night feeling is fading.

　C. Earning money is getting more difficult.

　D. Spending money is so fast and easy.

　30. Why does the author choose to write about what's happening to the wallet?

　A. It represents a change in the modern world.

　B. It has something to do with everybody's life.

　C. It marks the end of a time-honoured tradition.

　D. It is the concern of contemporary economists.

　31. What can we infer from the passage about the author?

　A. He is resistant to social changes.

　B. He is against technological progress.

　C. He feels reluctant to part with the traditional wallet.

　D. He feels insecure in the ever-changing modern world.
