首先,我们要认识到,并不是任何数列都可以求出其通项的,能够求出通项的只是一些特殊的数列;其次,由于求数列通项的问题题型众多,且灵活多变,解题难度较大,因此要想求通项,就必须掌握最基本的类型和方法.本文依据高中数学教材,结合近几年的高考对数列部分的考试要求、考查类型,将数列求通项问题的常见类型和方法进行整理、归纳,形成系统.以期对同学们的学习有所帮助,达到触类旁通之 First of all, we must realize that it is not possible to find any generalizations of any series, but only a few special ones can be obtained. Secondly, since there are so many problems in the generalization of items and their flexibility, So difficult to solve the problem, so in order to seek general items, we must master the most basic types and methods.This article based on high school mathematics textbooks, combined with the college entrance examination in recent years on the part of the test sequence requirements, test type, Common types of problems and methods to organize, summarize, form a system in order to help students learn to reach the analogy
