2014 高考会这样考 复习备考要这样做

等比数列及其前 n 项和

1.以等比数列的定义及等比中项为背景,考查等比数列的判定;2.运用 1.注意方程思想在解题中的应用;2.使用公式要注意公比 q=1 的情况;

基本量法求解等比数列问题;3.考查等比数列的应用问题. 3.结合等比数列的定义、公式,掌握通性通法.

1.等比数列的定义 如果一个数列从第 2 项起,每一项与它的前一项的比等于同一常数(不为零),那么这个数 列叫作等比数列,这个常数叫作等比数列的公比,通常用字母__q__表示. 2.等比数列的通项公式 设等比数列{an}的首项为 a1,公比为 q,则它的通项 an=a1· qn 1.


3.等比中项 若 G2=a· b_(ab≠0),那么 G 叫作 a 与 b 的等比中项. 4.等比数列的常用性质 (1)通项公式的推广:an=am· qn
-m

,(n,m∈N*).

(2)若{an}为等比数列,且 k+l=m+n (k,l,m,n∈N*),则 ak· al=am· an. ?1? ?an? 2 (3)若{an},{bn}(项数相同)是等比数列,则{λan}(λ≠0),?a ?,{an},{an· bn},?b ?仍是等 ? n? ? n? 比数列. 5.等比数列的前 n 项和公式 等比数列{an}的公比为 q(q≠0),其前 n 项和为 Sn, 当 q=1 时,Sn=na1; a1?1-qn? a1-anq 当 q≠1 时,Sn= = . 1-q 1-q 6.等比数列前 n 项和的性质 公比不为-1 的等比数列{an}的前 n 项和为 Sn,则 Sn,S2n-Sn,S3n-S2n 仍成等比数列, 其公比为__qn__. [难点正本 疑点清源] 1.等比数列的特征 从等比数列的定义看,等比数列的任意项都是非零的,公比 q 也是非零常数. 2.等比数列中的函数观点 利用函数、方程的观点和方法,揭示等比数列的特征及基本量之间的关系.在借用指数 函数讨论单调性时,要特别注意首项和公比的大小. 3.两个防范 (1)由 an+1=qan,q≠0 并不能立即断言{an}为等比数列,还要验证 a1≠0.

(2)在运用等比数列的前 n 项和公式时,必须注意对 q=1 与 q≠1 分类讨论,防止因忽略 q=1 这一特殊情形导致解题失误.

2 1.(2012· 辽宁)已知等比数列{an}为递增数列,且 a5 =a10,2(an+an+2)=5an+1,则数列{an}

的通项公式 an=________. 答案 2n 解析 先判断数列的项是正数,再求出公比和首项. ?1 ? a2 5=a10>0,根据已知条件得 2 q+q =5,解得 q=2. ? ?
8 9 n 所以 a2 1q =a1q ,所以 a1=2,所以 an=2 .

2.在等比数列{an}中,各项均为正值,且 a6a10+a3a5=41,a4a8=5,则 a4+a8=________. 答案 51
2 2 2 解析 由 a6a10+a3a5=41 及 a6a10=a2 8,a3a5=a4,得 a4+a8=41.因为 a4a8=5, 2 所以(a4+a8)2=a2 4+2a4a8+a8=41+2×5=51.

又 an>0,所以 a4+a8= 51. a c 3.已知 a,b,c 成等比数列,如果 a,x,b 和 b,y,c 都成等差数列,则 + =________. x y 答案 2 解析 令 a=1,b=3,c=9,则由题意,有 x=2,y=6. a c 1 9 此时 + = + =2. x y 2 6 4.(2011· 广东)已知{an}是递增等比数列,a2=2,a4-a3=4,则此数列的公比 q=________. 答案 2

? ?a2=2, 解析 由 a2=2,a4-a3=4,得方程组? ?a2q2-a2q=4, ?
?q2-q-2=0, 解得 q=2 或 q=-1.又{an}是递增等比数列,故 q=2. 5.(2012· 课标全国)已知{an}为等比数列,a4+a7=2,a5a6=-8,则 a1+a10 等于( A.7 答案 D B.5 C.-5 D.-7 )

?a4+a7=a1q3+a1q6=2, ? 解析 方法一 由题意得? 4 5 2 9 ? ?a5a6=a1q ×a1q =a1q =-8,
1 3 3 ? ? ?q =-2, ?q =-2, ∴? 或? ?a1=1 ? ? ?a1=-8, ∴a1+a10=a1(1+q9)=-7.

?a4+a7=2, ? 方法二 由? ? ?a5a6=a4a7=-8

2 p、q∈N*),则 am· an=ap· aq;若 m+n=2p(m,n,p∈N*),则 am· an=ap . a5 3 1 解 (1)设公比为 q,则 =q ,即 q3=- , a2 8 1?n-4 1 ∴q=- ,∴an=a5· qn-5=? ?-2? . 2 2 3 (2)∵a3a4a5=8,又 a3a5=a4 ,∴a4 =8,a4=2. 5 ∴a2a3a4a5a6=a4 =25=32.

在等比数列{an}中,

探究提高 在解决等比数列的有关问题时,要注意挖掘隐含条件,利用性质,特别是性 质“若 m+n=p+q,则 am· an=ap· aq”,可以减少运算量,提高解题速度. (1)已知各项均为正数的等比数列{an}中,a1a2a3=5,a7a8a9=10,则 a4a5a6 等于 A.5 2 答案 A 解析 把 a1a2a3,a4a5a6,a7a8a9 看成一个整体,则由题意,知它们分别是一个等比数列 的第 1 项,第 4 项和第 7 项,这里的第 4 项刚好是第 1 项与第 7 项的等比中项.因为数 列{an}的各项均为正数,所以 a4a5a6= ?a1a2a3?· ?a7a8a9?= 5×10=5 2. (2)已知 Sn 为等比数列{an}的前 n 项和,且 S3=8,S6=7,则 a4+a5+…+a9=________. 7 答案 - 8 解析 根据等比数列的性质,知 S3,S6-S3,S9-S6 成等比数列,即 8,7-8,S9-7 成等 1 1 7 比数列,所以(-1)2=8(S9-7).解得 S9=7 .所以 a4+a5+…+a9=S9-S3=7 -8=- . 8 8 8 题型三 等比数列的判定 例3 已知数列{an}的前 n 项和为 Sn,数列{bn}中,b1=a1,bn=an-an-1 (n≥2),且 an+Sn =n. (1)设 cn=an-1,求证:{cn}是等比数列; (2)求数列{bn}的通项公式. 思维启迪: (1)由 an+Sn=n 及 an+1+Sn+1=n+1 转化成 an 与 an+1 的递推关系, 再构造数 列{an-1}. (2)由 cn 求 an 再求 bn. (1)证明 ∵an+Sn=n,① ∴an+1+Sn+1=n+1.② ②-①得 an+1-an+an+1=1, ∴2an+1=an+1,∴2(an+1-1)=an-1, ∴ an+1-1 1 = ,∴{an-1}是等比数列. an-1 2 B.7 C.6 D.4 2 ( )

方法与技巧 1.等比数列的判定方法有以下几种: an+1 (1)定义: =q (q 是不为零的常数,n∈N*)?{an}是等比数列. an (2)通项公式:an=cqn-1 (c、q 均是不为零的常数,n∈N*)?{an}是等比数列. (3)等比中项法:a2 an+2(an· an+1· an+2≠0,n∈N*)?{an}是等比数列. n+1=an· 2. 方程观点以及基本量(首项和公比 a1, q)思想仍然是求解等比数列问题的基本方法: 在 a1, q,n,an,Sn 五个量中,知三求二. 3.在求解与等比数列有关的问题时,除了要灵活地运用定义和公式外,还要注意性质的应 用,以减少运算量而提高解题速度. 失误与防范 1.特别注意 q=1 时,Sn=na1 这一特殊情况.

解析 ∵a1+a2=a1(1+q)=30,a3+a4=a1q2(1+q)=60, ∴q2=2,∴a7+a8=a1q6(1+q)=[a1(1+q)]· (q2)3 =30×8=240. 6.在数列{an}中,已知 a1=1,an=2(an-1+an-2+…+a2+a1) (n≥2,n∈N*),这个数列的 通项公式是______________________________. ? n=1 ?1, 答案 an=? n-2 ?2×3 , n≥2 ? 解析 由已知 n≥2 时,an=2Sn-1① 当 n≥3 时,an-1=2Sn-2② an ①-②整理得 =3 (n≥3), an-1

?1, n=1, ? ∴an=? n 2 ? ?2×3 - , n≥2.
7.设等比数列{an}的公比为 q,前 n 项和为 Sn,若 Sn+1,Sn,Sn+2 成等差数列,则 q 的值为 ________. 答案 -2 解析 由已知条件得 2Sn=Sn+1+Sn+2, an+2 即 2Sn=2Sn+2an+1+an+2,即 =-2. an+1 三、解答题(共 22 分) 8.(10 分)已知等差数列{an}满足 a2=2,a5=8. (1)求{an}的通项公式; (2)各项均为正数的等比数列{bn}中,b1=1,b2+b3=a4,求{bn}的前 n 项和 Tn. 解 (1)设等差数列{an}的公差为 d,

? ?a1+d=2 则由已知得? .∴a1=0,d=2. ?a1+4d=8 ?
∴an=a1+(n-1)d=2n-2. (2)设等比数列{bn}的公比为 q,则由已知得 q+q2=a4, ∵a4=6,∴q=2 或 q=-3. ∵等比数列{bn}的各项均为正数,∴q=2. b1?1-qn? 1×?1-2n? n ∴{bn}的前 n 项和 Tn= = =2 -1. 1-q 1-2 1 9.(12 分)已知数列{an}的各项均为正数,且前 n 项和 Sn 满足 Sn= (an+1)(an+2).若 a2, 6 a4,a9 成等比数列,求数列{an}的通项公式. 1 解 因为 Sn= (an+1)(an+2),① 6 1 所以当 n=1 时,有 S1=a1= (a1+1)(a1+2), 6

2 当 a1=1 时,an=1+3(n-1)=3n-2,此时 a4 =a2a9 成立. 2 当 a1=2 时,an=2+3(n-1)=3n-1,此时 a4 =a2a9 不成立.

所以 a1=2 舍去.故 an=3n-2. B 组 专项能力提升 (时间:25 分钟,满分:43 分) 一、选择题(每小题 5 分,共 15 分)

4 项和为 15 A. 或 4 8 答案 C

( 40 B. 或 4 27 40 C. 27 15 D. 8

解析 设数列{an}的公比为 q. 当 q=1 时,由 a1=1,得 28S3=28×3=84. 而 S6=6,两者不相等,因此不合题意. 28?1-q3? 1-q6 当 q≠1 时,由 28S3=S6 及首项为 1,得 = .解得 q=3.所以数列{an}的通项 1-q 1-q 公式为 an=3n-1. ?1? 1 1 1 40 所以数列?a ?的前 4 项和为 1+ + + = . 3 9 27 27 ? n? 1 m 2.已知方程(x2-mx+2)(x2-nx+2)=0 的四个根组成以 为首项的等比数列,则 等于( ) 2 n 3 3 2 2 A. B. 或 C. D.以上都不对 2 2 3 3 答案 B 解析 设 a,b,c,d 是方程(x2-mx+2)(x2-nx+2)=0 的四个根,不妨设 a<c<d<b,则 1 a· b=c· d=2,a= ,故 b=4,根据等比数列的性质,得到:c=1,d=2,则 m=a+b 2 9 9 m 3 m 2 = ,n=c+d=3 或 m=c+d=3,n=a+b= ,则 = 或 = . 2 2 n 2 n 3 3.设{an}是任意等比数列,它的前 n 项和、前 2n 项和与前 3n 项和分别为 X,Y,Z,则下列 等式中恒成立的是 A.X+Z=2Y B.Y(Y-X)=Z(Z-Y) C.Y2=XZ D.Y(Y-X)=X(Z-X) 答案 D 解析 对于含有较多字母的选择题,可以取满足条件的数字代替字母,代入验证,若能 排除三个选项,则剩下的唯一选项就一定正确;若不能完全排除,则可以取其他数字继 续验证排除.
