Tollu, D. T.Yazlik, Y.Taskara, N.2020-03-262020-03-2620140096-30031873-5649https://dx.doi.org/10.1016/j.amc.2014.02.001https://hdl.handle.net/20.500.12395/31033In this paper, we mainly consider the systems of difference equations x(n+1) = 1+p(n)/q(n), y(n+1) = 1+r(n)/s(n), n is an element of N-0, where each of the sequences p(n); q(n); r(n) and s(n) represents either the sequence x(n) or the sequence y(n), with nonzero real initial values x(0) and y(0). Then we solve fourteen out of sixteen possible systems. It is noteworthy to depict that the solutions are presented in terms of Fibonacci numbers for twelve systems of these fourteen systems.
