在等差数列{an}中,与不等式相关的客观题,频频出现在各地市高二模块或高三阶段性考试中,鉴于数列与不等式的交汇命题,使得一些学生在解决问题时常常思路受阻或遇到无法着手的局面,为此笔者将两个客观题从多个角度进行求解,以飨读者.例1已知等差数列{an}满足a9a8<-1,若其前n项和Sn有最大值,则使Sn>0的正整数n的 In the arithmetic sequence {an}, the objective questions related to inequality frequently appear in the High School II modules or high school examinations in different cities. In view of the intersection proposition of the series and the inequality, some students often block their thinking or solve the problem To unable to start the situation, for which the author will solve the two objective problems from multiple angles to readers.Example 1 Known arithmetic sequence {an} satisfy a9a8 <-1, if the first n and Sn has the largest Value, then make Sn> 0 positive integer n
