“新定义型”数列是近几年高考中经常出现的而中学数学尚未介绍的一类数列,此类试题常常是以“新定义型”数列的定义或性质为载体,考查学生的创新能力和运用数学知识综合解决问题的能力.本文将结合具体的例子介绍几种主要的“新定义型”数列,旨在揭示解题方法,举一反三. “New Defined ” series is a series of frequently appeared in college entrance examination in recent years and has yet to be introduced in secondary school mathematics. Such questions are often based on the definition or nature of the “new definition” series as a test for students Innovation capacity and the ability to use mathematical knowledge to solve problems comprehensively.This paper will introduce several major “new definition type” series with specific examples to reveal the problem solving methods, giving top priority.
