Introduction Difference equations appear naturally as discrete analogues and in the numerical solutions of differential and delay differential equations having applications in biology ecology physics and so forth 1 . The study of nonlinear difference equations is of paramount importance not only in their own field but in understanding the behavior of their differential counterparts. There has been a lot of work .
