The Pell sequence $(P_n)_{n\geq 0}$ is the second order linear recurrence defined by $P_n=2P_{n-1}+P_{n-2}$ with initial conditions $P_0=0$ and $P_1=1$. In this talk, we present some recent work on a generalization of the Pell sequence called the $k$-Pell sequence $(P_n^{(k)})_{n}$ which is generated by a recurrence relation of a higher order. We report about some arithmetic properties of $(P_n^{(k)})_{n}$ and study some Diophantine equations involving Fibonacci and $k$-Pell numbers.

Joint work with J. L. Herrera (U. Cauca, Colombia) and F. Luca (Wits, South Africa and UNAM, Mexico).
