近几年的高考试卷中,我们分析到,数列求和综合考查了函数方程、化归转化、数学归纳、分类讨论等多种数学思想方法,以至于数列求和成为高考的热点内容.数列求和试题命题原则立足于课本,高于课本,具有较强的综合性.常见的数列求和的方法有(等比和等差数列的求和)公式法、错位相减法、倒序相加法、分组求和法、裂项相消法、数学归纳法. In recent years, the college entrance examination papers, we analyzed, summed up the series of comprehensive examination of the function equation, conversion, mathematical induction, classification and discussion of a variety of mathematical thinking, that summation of the series became the hot topic of the college entrance examination. And test questions proposition based on the textbook, higher than the textbook, with a strong synthesis of common sequence summation method (sum of geometric and arithmetic sequence) formula method, the dislocation subtraction method, reverse order addition method, Subgroup Summation, Crack Elimination, Mathematical Induction.
