摘要
在数学建模中常常用数列的递推公式求数列通项,由递推公式求数列通项既可考查等价与化归数学思想,又能加深考生对等差与等比数列的理解,因而这类题目在高考和数学竞赛中经常出现.故以一阶线性递推数列的通项公式为基础,推导出二阶线性递推数列的通项公式.
Seeking the general term formula through the recurrence formula of a sequence is often used in mathematical modeling,it not only examines equivalence and transforming thought but also makes deeply understand arithmetic and geometric sequence better,so such topics is often appeared in college entrance examination and mathematics competition.This paper has derived the general term formula of second-order linear recurrence sequence which is based on the general term formula of first-order linear recurrence sequence.
