简单递推数列通项的求法

The Method of Simple Series the General Term

数列是高中代数的重要内容之一，也是初等数学与高等数学的衔接点，数列通项公式直接表述了数列的本质，是给出数列的一种重要方法。因此，求数列的通项公式是高中数学中最为常见的题型之一，它既考察等价转换与化归的数学思想，又能反映对数列的理解深度，具有一定的技，引生。本文介绍了几种常见的递推数列通项的求法。

The sequence is one of the important content of the school algebra, and it is also the link points of the elementary mathematics and the higher mathematics, the sequence the general term formula directly expressed the essence of the series, and is an important method to give the sequence. Therefore, the general term formula for the sequence is one of the most common questions in the high school mathematics; it is both the investigation of equivalent conversion and transforming mathematical thoughts, and reflecting on the depth understanding of the sequence, which has certain skills. This paper introduces several common recursion sequence induces the general term.
