极限分析法是处理无穷等比数列的一个有效方法. 设{an)是公比为q的无穷等比数列,将an+1/an=q两边取极限,得 这说明等比数列中an+1/an的极限存在.且就是公比q.
Limit analysis method is an effective method to deal with infinite number sequence. Let {an) be an infinite number sequence with a common ratio of q, and take the extremes of an+1/an=q to get the limit. The limit of 1/an exists and is the ratio q.
