应用“化归”思想求由递推式所确定的数列的通项公式

The Solution to the General Formula of Sequence Determined by Recursive Formula Based on the Idea of Transformation and Classification

数列是高等数学中学习极限、定积分、级数等知识的基础,也是高中数学中的一个重点与难点,求数列的通项公式是常见的题型;本文用化归的思想求几种形式的递推式所确定的数列的通项公式。

Sequence is an emphasis of high school mathematics and a difficulty as well. How to solve the general formula of sequence is a common type of tests. This article gives the solution to the general formula of sequence determined by recursive formula of some forms by applying the idea of transformation and classification.
