在2016年高考数列解答题中,数列的主要内容包括数列的概念与简单表示法、等差数列、等比数列、数列求和、数列的综合运用。下面,笔者就2016年高考数列解答题进行简单的分析与总结。例1(2016年高考数学全国卷Ⅰ)已知{a_n}是公差为3的等差数列,数列{b_n}满足b_1=1,b_2=1/3,a_nb_(n+1)+b_(n+1)=nb_n。(Ⅰ)求{a_n}的通项公式; In the 2016 college entrance examination series of questions, the main contents of the series include the concept of sequence and simple notation, arithmetic sequence, geometric series, series summation, the comprehensive use of series. Below, the author on the 2016 college entrance examination series of questions to conduct a simple analysis and summary. {A_n} is an arithmetic sequence with a tolerance of 3, and the sequence {b_n} satisfies b_1 = 1, b_2 = 1/3, a_nb_ (n + 1) + b_ (n +1) = nb_n. (Ⅰ) Find the general formula of {a_n};
