数列是高中数学中很重要的一部分,在高考中每年都有所体现.其实,数列是函数概念的继续和延伸,数列的通项公式及前n项和公式都可以看作特殊的函数,数列问题的解决是函数方程思想的最好体现.通项及求和是数列中最基本也是最重要的问题之一,是高考对数列问题考查中的热点.对于数列求和的问题,常是学生感觉困难的部分,那么一般有哪些方法呢?求和的前提是首先要分析数列的通项公式,在此基础上有以下一些方法.
In fact, the series is the continuation and extension of the concept of function, the general formula of the series and the first n terms and formulas can be regarded as a special function, the number of columns The solution of the problem is the best manifestation of the functional equation thought.And the summation and summation are one of the most basic and most important problems in the series.It is the hot spot in the examination of the series of questions in the college entrance examination.For the problem of the summation of the series, Feel difficult part, so what are the general methods? The premise of summation is to first analyze the general formula of the sequence, on the basis of the following methods.
