We study the global stability, the periodic character, and the boundedness character of the positive solutions of the difference equation xn+1=(αβxn)/(γδxnxnk),n=0,1,2,,k{1,2,}, in the two cases: (i) δ0,α>0,γ>β>0; (ii) δ0,α=0,γ,β>0, where the coefficients α,β,γ, and δ, and the initial conditions xk,xk+1,,x1,x0 are real numbers. We show that the positive equilibrium of this equation is a global attractor with a basin that depends on certain conditions posed on the coefficients of this equation.
