数列知识是高考中的重点内容,也是必考内容,其中递推数列是数列问题的重中之重.掌握求递推数列的通项公式的转化方法与规律,对于解决数列通项公式问题具有重要作用.由递推数列求通项,形式多变、解法灵活、技巧性强,解法的关键是将递推关系式转化为我们熟知的等差型、等比型、累加型、累乘型等数列形式,然后求出数列的通项公式.此类问题主要有以下 Serial knowledge is the key content in the college entrance examination, but also the necessary content, which recursive number sequence is the top priority of the number of series. Grasp the number of recursive sequence formula conversion method and law, to solve the problem The key role of the sequence by recursive seeking items, the form of changeable, flexible solution, highly skilled, the key to solution is to convert the recurrence of the equation into our well-known isometric, isometric, cumulative, tired multiply Such as the number of forms, and then calculate the general formula of the series. Such problems are the following
