Periodic Coefficients and Random Fibonacci Sequences

open access: yes, 2012
The random Fibonacci sequence is defined by t_1 = t_2 = 1 and t_n = ± t_{n–1} + t_{n–2} , for n ? 3, where each ± sign is chosen at random with P(+) = P(–) = 1/2. We can think of all possible such sequences as forming a binary tree T.

Generalizing Random Fibonacci Sequences

open access: yes, 2023
We consider generalized Fibonacci sequences with recurrencerelation xn+p+1 = xn+p + xn, which have growth rates of the formlimn→∞ |xn|1/n that behave similarly to the golden ratio, (1 + √5)/2.Following Makover and McGowan’s analysis of the random ...

The p-adic valuation of Lucas sequences

open access: yes, 2016
Let (un)n≥0 be a nondegenerate Lucas sequence with characteristic polynomial X2 − aX − b, for some relatively prime integers a and b. For each prime number p and each positive integer n, we give simple formulas for the p-adic valuation νp(un), in terms ...

Formulas for Fibonacci-Like Sequences Produced by Pascal-Like Triangles

open access: yes, 2022
In this paper we are going to present three formulas to express Fibonacci-like sequences with the Fibonacci sequence. We constructed Pascal-like triangles using probabilities of a game, and these Pascal-like triangles can be considered generalizations ...

A Family of Fibonacci-Like Sequences

open access: yesThe Fibonacci Quarterly, 1987
We consider the recurrence relation $G_n = G_{n-1} + G_{n-2} + \sum_{j=0}^k \alpha_j n^j$, where $G_0 = G_1 = 1$, and we express $G_n$ in terms of the Fibonacci numbers $F_n$ and $F_{n-1}$, and in the parameters $\alpha_1,\ldots,\alpha_k$.

On the Fibonacci and the Generalized Fibonacci Sequence

open access: yesJournal of Nepal Mathematical Society
Fibonacci numbers and their sequence are found abundantly in nature. There is a close relation among the Golden, Fibonacci, and Lucas ratios. Such ratios are inherent to design, architecture, construction, and even to the beauty of different natural and manmade solid objects.

On truncated fibonacci sequences

open access: yes, 2007
We prove some theorems concerning truncated Fibonacci sequences, which are defined below in Section 2. We also state some conjectures concerning the period (mod m) of truncated Fibonacci sequences, where the integer m is greater than or equal to 2.

A class of Fibonacci-type sequences

open access: yesDiscrete Mathematics, 1974
Let \(\{L_n : n\ge 1\}\) be a sequence of the form \[ L_n= \min\left( \sum_{j=1}^p L_{n-a_j}\quad (n>e),\quad \sum_{j=1}^q L_{n-b_j}\quad (n>e)\right), \] where \(\{a_j\}\) and \(\{b_j\}\) are positive integers, and \(e = \max_{i,j} \{a_i ,b_j\}\). A necessary and sufficient condition on the integers \(\{a_j\}\) and \(\{b_j\}\) is given so that, for ...
