数列极限在每年高考中都有所涉及,本文结合近年的高考题,根据数列极限不同形式,分类归纳如下技巧,以揭示这类问题求解的一般规律。一、求和型求解策略:关键是变无限项为有限项,先求和再求极限。 The limit of the series is involved in the annual college entrance examination. This paper combines the recent college entrance examination questions, according to the different forms of the limit of the series, and classifies and summarizes the following techniques to reveal the general laws of solving such problems. First, the sum-solving solution strategy: The key is to change the infinite term is a finite term, the first sum and then find the limit.
