解数学题是一个不断转化的过程,化陌生为熟悉,化变态为常态,化未知为已知,合理有效的转化是数学解题的核心思想。数列通项公式是研究数列相关性质的基础,因而熟练掌握求数列通项公式的方法是学习数列的一项基本技能,也是高考考查的重点。下面,笔者主要讨论递推关系为a_1=a,a_(n+1)=Aa_n+B(A、B是常数,且AB≠0,A≠1)的数列{a_n}的通项公式的求法。
Solving mathematical problems is a continuous process of transformation, familiarization of strangers, abnormal perversion as a normal, unknown as known, reasonable and effective conversion is the core idea of mathematical problem solving. The sequence formulas are the basis for the study of the nature of the series of numbers. Therefore, it is a basic skill to learn the series that the master method of formulating the formula is also the focus of the college entrance examination. In the following, the author mainly discusses the general formula of the sequence {a_n} in which the recursion relations are a_1 = a, a_ (n + 1) = Aa_n + B (A, B are constants and AB ≠ 0, A ≠ 1) .
