Abstract

Since the Fibonacci\mathrm{Fibonacci} sequence has good properties, it's important in theory and applications, such as in combinatorics, cryptography, and so on. In this paper, for the generalized Fibonacci sequence {Wn(a,b,p,q)}\left\{W_n\left(a,b,p,q\right)\right\}, by using elementary methods and techniques, we respectively give the asymptotic estimation values of (k=n1Wmk+ld)1\left(\sum\limits_{k=n}^{\infty}\frac{1}{W_{mk+l}^d}\right)^{-1} and (k=n(1)kWmk+ld)1\left(\sum\limits_{k=n}^{\infty}\frac{\left(-1\right)^k}{W_{mk+l}^d}\right)^{-1}, which generalize the asymptotic estimation results of Yuan et al. \cite{A14} in 2025.
