关于满足条件a_(m+k)=λ_1a_(n+k-1)+λ_2a(n+k-2)+…λ_ka_n的一元线性递归数列{a_n}的通项公式,已经有了很好的结论。本文对二重数列及满足简单条件A_m~n=λ_1A_(m-1)~n+λ_2A_(m-1)~(n-1)的二重线性递归数列的通项公式得到两个有用的定理。
With respect to the general formula for the unary linear recursive sequence {a_n} satisfying the conditions a_ (m + k) = λ_1a_ (n + k-1) + λ_2a (n + k-2) + ... λ_ka_n, it has been well concluded . In this paper, we obtain two useful theorems for the dichotomous sequence and the general formula that satisfies the two linear recursive sequences A_m ~ n = λ_1A_ (m-1) ~n + λ_2A_ (m-1) ~ (n-1) .
