递推关系是给出数列的一种重要方式.综观近几年的高考试题考查递推数列的题型多样,由递推关系求数列通项,方法也比较灵活,是数列考题中常考的热点,也是考察数列与其它知识综合的基点与突破口.本文通过十种递推关系类型介绍了运用累加法、累乘法、迭代法、构造法等求数列通项.
Recursive relationship is an important way to give out the number of columns.Review of the recent years, college entrance examination exam questions recursive sequence of the various types of questions, recursive relationship between the number of items, the method is also more flexible, is the number of exam questions often hot , But also the basic point and the breakthrough point for examining the integration of series and other knowledge.This paper introduces the use of summation, multiplication, iteration and construction methods to solve the general term through the ten types of recursion relations.
