数列是高中数学的重要内容之一,它往往可以与多种知识进行整合,也体现了高考数学命题的原则:在知识网络的交汇处命题,本文拟例说明,旨在熟悉题型特征,掌握解题方法.1与函数的整合例1已知函数f(x)=1+log2x,设数列{an}满足an=f-1(n)(n∈N*),则数列{an}的前n项和Sn=()A2n-1-1;B2n- The series is one of the important contents of high school mathematics, it can often be integrated with a variety of knowledge, but also embodies the principle of college mathematics proposition: the proposition at the intersection of the knowledge network, this article is intended to explain, designed to familiarize with question type features, master Problem Solving Method 1. Integration with Functions Example 1 The function f(x)=1+log2x is known, and the set {an} satisfies an=f-1(n)(n∈N*), then the sequence {an} Top n items and Sn=() A2n-1-1; B2n-
