压缩映像原理在递推数列极限中的应用

Application of contraction mapping principle to recursion sequence of number

结合递推数列的特点,将压缩映像原理运用到数列极限问题中去,使关于数列极限存在性和求解问题得到更快、更简易的解决。

Combining the features of recursion sequence of number, applied the contraction mapping principle to the limit of sequence of number, arriving at a more prompt and easier approach to existence of limit of sequence of number and its solution
