递推数列是最近几年活跃在各种考试中,但从考试结束后学生反映的情况来说并不理想,究其原因,大部分同学只记得用特征方程,但特征方程不是高中的概念,对其本质学生并不是十分了解,因此有必要探究一下二阶线性递推数列特征方程的来源与应用。一、对于二阶线性递推数列
Recursive series in recent years are active in a variety of examinations, but from the examination after the students reflect the situation is not ideal, the reason, most students only remember to use the characteristic equation, but the characteristic equation is not the concept of high school, For its essence students are not very understanding, so it is necessary to explore the second order linear recurrence series eigenvalue source and application. First, for the second order linear recursion sequence
