数列的综合应用问题,包含等差数列和等比数列的综合,数列和函数、不等式的综合,与数列相关的应用题,是高考考查的热点之一.对学生观察、归纳、类比、联想等数学思想的要求较高,本文就数列的综合应用进行一些分析.一、等差、等比数列的综合问题例1已知等差数列{a n}的公差不为零,a1=25,且a1,
Comprehensive application of series of questions, including the arithmetic sequence and arithmetic series, series and function, the inequality of the synthesis, and the sequence of application questions, is one of the hot spots for the college entrance examination examinations of students, induction, analogy, association, etc. Mathematical thinking of the higher requirements of this article on the comprehensive application of the number of columns for some analysis. First, the arithmetic and arithmetic sequence of the integrated problem Example 1 known differential sequence {an} tolerance is not zero, a1 = 25, and a1 ,
