 Abstract. In this paper we study the behavior of the difference equation $$x_{n+1}=ax_{n}+{bx_{n}x_{n-2}\over cx_{n-1}+dx_{n-2}}, n=0,1,\ldots,$$ where the initial values $x_{-2}$, $x_{-1}$, $x_{0}$ are arbitrary positive real numbers and $a$, $b$, $c$, $d$ are positive constants. Also, we give the solution of some special cases of this equation.
