Abstract
In this paper we study some properties of solutions of difference equation
xn+1 = ax(n-2) + bx(n-2)x(n-3)/cx(n) + dx(n-3), n = 0, 1,...,
where the initial conditions x(-3), x(-2), x(-1), x(0) are arbitrary positive real numbers and a, b, c, d are constants. Also, we give the expressions of solutions for some special cases of this equation.
