Query: Identities for second order recurrence sequences   We derive several identities for arbitrary homogeneous second order
recurrence sequences with constant coefficients. The results are then applied
to present a unified study of six well known integer sequences, namely the
Fibonacci sequence, the sequence of Lucas numbers, the Jacobsthal sequence, the
Jacobsthal-Lucas sequence, the Pell sequence and the Pell-Lucas sequence.
