摘　　要：对于求极限问题,没有统一的方法,只能根据具体情况进行具体分析和处理。有些数列,常常是利用递推的形式给出的,本文专门处理求该类数列的极限问题,主要有写出通项求极限、利用存在性求极限、替换与变形求极限等常规方法。The limit problems must be calculated flexibly because there is no unified method.This paper specially solves the limit problems of sequences of recurrence form.The routine calculating methods include finding the limits through writing general term,finding the limits by means of existence,finding the limits by means of substitution and formula deformation.
