数列问题是近年来高考的热点与难点之一,而已知数列递推公式求通项的问题更是倍受青睐。该类问题一般都是利用“化归”的思想来解决,其间技巧性强,学生很难掌握解决此类问题的通性通法.本文从一般情况给出求解一类递推数列——齐次线性递推数列通项的一般方法.
The series problem is one of the hotspots and difficulties in the college entrance examination in recent years, and the problem of known universal series recurrence formulas is even more popular. This type of problem is generally solved by using the idea of “returning to”, and it is difficult to master the general method to solve such problems. This article gives a general solution to solve a class of recursive sequences - - General methods for homogeneous linear recursive sequence general terms.
