高一年级 第三章 数学 数 列 总 复 习 (二) 授课者:贺仁亮 例2: 等比数列 {a n } 中,各项均为 正数,且 a6 ? a10 ? a3 ? a5 ? 41, a4 ? a8 ? 4 ,求 a 4 ? a8 例3:设等差数列{an}的前n项和 为Sn.已知a3=12, S12>0,S13<0. (Ⅰ)求公差d的取值范围; (Ⅱ)指出S1,S2,…,S12,中哪一个 值最大,并说明理由. 例4.三数成等比数列,若将第三个 数减去32,则成等差数列,若再将 成等差的三数的第二个数减去4. 则又成等比数列,求原来三数. 例4.三数成等比数列,若将第三个 数减去32,则成等差数列,若再将 成等差的三数的第二个数减去4. 则又成等比数列,求原来三数. 分析:关键是三数如何设法以利于 运算 例 4.三数成等比数列,若将第三 个数减去32,则成等差数列,若再 将成等差的三数的第二个数减去 4.则又成等比数列,求原来三数. 分析:关键是三数如何设法以利于 运算 答案 : 2 , 10 , 50 , 或 20/9 , 26/9 , 328/9 例 4.三数成等比数列,若将第三个数 减去32,则成等差数列,若再将成等差 的三数的第二个数减去4.则又成等 比数列,求原来三数. 分析:关键是三数如何设法以利于运算 答案 : 2 , 10 , 50 , 或 20/9 , 26/9 , 328/9 题结 : 若干数成等差若干数成等比的 问题混在一起时,设法上一般以成等差 为基础进行设元. 例5 ? { an } 满足an=n, 作一个新数列 数列 { bn },使b1= a1 ,b2 = a2 + a3 , b3= a4 + a5+a6, 求bn 例6 等差数列{bn} 中,a1=1,d=2依次 抽出这个数列的第1,3, 32, …, k - 1 3 项,组成数列{ bn },求数列 {bk}的通项公式及前n项的和Sn 作业: 1.在等差数列{an}中,公差 d ? 0 前6项的和S6=0,若am ,am+1 ,a2m三 项成等比数列,求m的值 2 : 若互不相等的三个实数的积为 – 8 ,这 三个实数适当安排后,可以成等差数列,也 可以成等比数列,则当这三个数成等差数 列排列时依次为_____ . 3.数列{an}是等比数列,首项a1 > 0,公 比q = 2 ; 数列{bn}是等差数列 ,公差 d = 1/3 ,若logxan – bn = logxa1 – b1 , 求x的值
