On the (s,t)-Pell and (s,t)-Pell-Lucas numbers by matrix methods [PDF]

In this paper, we investigate some generalization of Pell and Pell-Lucas numbers, which is called (s, t)-Pell and (s, t)-Pell-Lucas numbers, and we define the 2 × 2 matrix W, which satisfy the relation W = 2sW+ tI.

On Pell and Pell-Lucas numbers

In this work, we consider the linear recurrent sequences with constant coefficients of order 2, focusing on those defining Pell and Pell-Lucas numbers. In this context, we have examined the corresponding Binet formulas and the possibilities for a Pell or

ON GENERALIZED LUCAS AND PELL-LUCAS SEQUENCES

, 2019
In this paper, we define the generaziled Lucas sequences and the Pell-Lucas sequences. Further we give Binet-like formulas, generating function, sums formulas and some important identities which involving the generalized Lucas and Pell-Lucas ...
