数列知识是高考的重点考查对象,多与函数、方程、不等式、二项式定理等知识联系在一起,解决该类问题往往要先确定数列的通项.由递推关系确定数列的通项主要由生成、转化和叠代等思想方法来处理,本文就近几年高考题中常涉及到的通项求法予以归纳和总结,以供参考.1叠加法例1已知 The series of knowledge is the focus of the college entrance examination. It is often associated with functions, equations, inequalities, binomial theorems and other knowledge. To solve this type of problem, it is often necessary to first determine the general terms of the series. The recurrence relationship determines the general terms of the series. It is processed by the methods of generation, transformation, and iteration. This article summarizes and summarizes the general term methods commonly used in college entrance examination questions in recent years for reference.
