数列是高中数学的重要内容,是学习高等数学的基础,它起着承上启下的作用数列求和着重考查学生的运算能力和归纳抽象能力,由于它有很强的技巧性,掌握起来有一定困难,常成为各类数学考试以及竞赛中出题的热点。本文根据数列求和的常见题型,归纳总结了它的基本方法和技巧。一、分组求和法有一类数列,既不是等差数列,也不是等比数列,若将这类数列适当拆开,能
The series is an important part of high school mathematics, and it is the basis for learning advanced mathematics. It plays a role in linking up with others. It focuses on the students’ computational ability and inductive abstraction ability. Because of its strong skill, it has certain difficulties in mastering. It often becomes a hot topic in various math exams and competitions. This article summarizes its basic methods and techniques based on the common questions of the series summation. First, the group summation method has a series of numbers, which are neither equal arithmetic sequences nor equal number sequences. If such numbers are appropriately disassembled, they can
