Abstract
It is shown that every well-defined solution to the second-order difference equation in the title, when (A(n))(n is an element of 0) is a two-periodic sequence such that max{A(0), A(1)} >= 0, is eventually periodic with period two. In the case max{A(0), A(1)} < 0 it is shown the existence of unbounded solutions, by describing all solutions in terms of A(0), A(1), x(-1) and x(0).
