关于广义斐波那契数

On Generalized Fibonacci Numbers

Jerico B. Bacani, Julius Fergy T. Rabago

摘要:

利用$k$ -广义Fibonacci数或$k$ -nacci数给出了$k$-广义Fibonacci-like数列的$n^{th}$项的一个公式,并利用新导出的公式证明了该数列连续项之比的极限趋于方程$x + x^{-k} = 2$的一个根.然后,我们将结果推广到$k$ -广义Horadam($k$ GH)和$k$ -广义Horadam-like($k$ GHL)数.在处理$k$ GH和$k$ GHL连续项比的极限时,由于Z而引入了一个引理。Wu和H.张[8]将被雇用。最后,我们指出,对于$k$ -周期$k$ -二元Fibonacci序列,也可以得到类似的结果.

英文摘要:

We provide a formula for the $n^{th}$ term of the $k$-generalized Fibonacci-like number sequence using the $k$-generalized Fibonacci number or $k$-nacci number, and by utilizing the newly derived formula, we show that the limit of the ratio of successive terms of the sequence tends to a root of the equation $x + x^{-k} = 2$. We then extend our results to $k$-generalized Horadam ($k$GH) and $k$-generalized Horadam-like ($k$GHL) numbers. In dealing with the limit of the ratio of successive terms of $k$GH and $k$GHL, a lemma due to Z. Wu and H. Zhang [8] shall be employed. Finally, we remark that an analogue result for $k$-periodic $k$-nary Fibonacci sequence can also be derived.
