Global Stability of x sArx pq1rx1r p nq1 n ny1

We obtain a general global attractivity result for a difference equation of the form xnq1sf xn, xny1., ns0, 1, . . . , where f x, y.is strictly decreasing in both arguments. The result applies to the difference equation xnq1sArxnpq1rx1nryp1, ns0, 1, . . . , where xy1, x0, Ag 0, `.and p)1
