一类线性递推数列求通项的特征根法的探讨

摘要

The solution to general term of linear recursion sequences is not only a key but a difficult point in the university entrance exam.The solution to such kind of mathematical problem is tedious and easy to make mistakes.This paper probes into the common eig%求线性递推数列的通项是高考中的重点和难点，此类问题的解法繁琐且易出错，本文探讨了常见的特征根法，给出了相关例子，说明其普遍性、实用性。
