浅析数列求和方法

Analysis on Method of Sequence of Number Summation

数列求和问题有时比较麻烦,甚至无从下手。抓住数列不同的特点,找出规律就可以比较容易地求出来。根据数列的不同特点,给出数列求和的两种方法——添因子求和法和去因子求和法。

Sometimes, the problem of sequence of number summation is a little troublesome, even there is no way to deal with it. However, catching the different characters of sequence of number and finding the rule will make it easy to solve the problem. This paper, based on different characters of sequence of number, gives two methods of sequence of number summation： add factor summation and minus factor summation.
