Recurrence Relations for the Squares of the Horadam Numbers and Some Associated Consequences

Abstract

Abstract We derive recurrence relations for the squares of the Horadam numbers wn2 w_n^2 , where the Horadam sequence wn is such that the numbers wn, for n ∈ ℤ, are defined recursively by w0 = a, w1 = b, wn = pwn−1 − qwn−2 (n ≥ 2), where a, b, p and q are arbitrary complex numbers with p ≠ 0 and q ≠ 0. Some related results emanating from the recurrence relations such as reciprocal sums, partial sums, and sums with double binomial coefficients are also presented.
