In this paper we present some identities involving terms of k-Pell, k-Pell-Lucas
and Modified k-Pell sequences. We also give some results on the column and row
norms of Hankel matrices which entries are numbers of these sequences.

In this paper we present new families of sequences that generalize the Jacobsthal and the Jacobsthal-Lucas numbers and establish some identities. We also give a generating function for a particular case of the sequences presented.
