数列通项的求解是数列知识的重要内容.通常较为简单的试题可直接用等差或等比数列公式就能求出数列的通项公式,稍微复杂的试题则需要对数列进行变形和重新构造再进行求解.以下就简单介绍通过递推式的变换求数列通项的几种较典型的方法.一、累加法
The solution to the general term of sequence is an important part of the knowledge of sequence.Generally simple questions can be obtained directly by using arithmetic equations such as arithmetic or geometric series and slightly complicated questions need to be deformed and reconstructed And then solve the following a brief introduction by recursive transformation of the number of items listed in several typical methods.
