数列可以看作一个定义域为非零自然数集N*或N*的予集的函数,当自变量从小到大依次取值对对应的一列函数值,因此数列与函数之间存在着密切的联系.在数列解题过程中,若能利用这种关系.可以使数列问题化繁为简,化难为易,本文就此作一探讨,供同学们借鉴。 A sequence of numbers can be seen as a function of a given set whose domain is a set of non-zero natural numbers N* or N*. When the arguments are taken from the smallest to the largest, the values ​​are assigned to the corresponding column of function values, so there is a close relationship between the series and the function. In the course of solving a series of questions, if we can use this relationship, we can simplify the series of questions and make it difficult to understand. This article makes a discussion on this for students to learn from.
