纵观历年高考,各种数列问题在很多情形下,首先就是对数列通项公式的求解.特别是在一些综合性比较强的数列问题中,数列通项公式的求解问题是一类高考重点考查题型,也往往是解决数列难题的瓶颈.因此,对一些常见的递推数列进行归纳和研究是必要的且大有益处的.本文就利用数列的递推公式来求解通项公式作简要的探究. Throughout the year college entrance examination, a variety of series of questions in many cases, the first is the formula for solving the sequence of items, especially in some of the more comprehensive series of problems, the series of formulas to solve the problem is a key examination of the entrance examination Problem type is often the bottleneck to solve a series of difficult problems.Therefore, it is necessary and helpful to generalize and study some common recursive sequences.In this paper, we use the sequence recursion formula to solve the general formula, Explore.
