数列是高中数学的重要内容之一,也是高考考查的重要内容之一,高考对数列的考查主要涉及等差数列、等比数列的通项,前狀项和的相关问题,以及数列与其他主干知识相结合的综合问题,如2008、2009年江苏高考考查了数列中的整除问题.这类问题在高三复习中经常闯入我们的视线,而学生解决这类问题往往束手无策.本文介绍处理数列中整除问题的几种常见方法.1估计范围后再枚举先估计出某个正整数的范围,特别是要估计
The series is one of the important contents of high school mathematics, and it is also one of the important contents of the college entrance examination. The examination of the college entrance examination mainly involves arithmetic series, the general term of the geometric series, the related problems of the preceding items, and the series and other trunks. The comprehensive problem of the combination of knowledge, such as the Jiangsu and China college entrance exams in 2008 and 2009, examined the problem of integer division in the series. Such questions often fall into our line of sight during the third year of review. Students are often unable to solve this type of problem. This article describes the processing sequence. There are several common ways to divide the problem. 1 Enumeration before estimating the range first estimates the range of a positive integer, especially to estimate
