Abstract

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