Abstract
In this paper, we study the behavior of the difference equation x(n+1 )= ax(n) + bx(n)x(n-1)/Cx(n-1) + dx(n-2),( )n = 0,1, ..., where the initial conditions x(-2), x(-1), x(0) are arbitrary positive real num bers and a, b, c, d are positive constants. Also, we give the solution of some special cases of this equation.
