This paper is concerned with the nonlinear delay difference equations with positive and negative coefficients x(n + 1) - x(n) + p(n)f(x(n - k)) - q(n)f(x(n - l)) = 0, n >= n(0). (*) Sufficient conditions are obtained under which every solution of Eq. (*) is bounded and tends to a constant as n -> infinity. (C) 2010 Elsevier Ltd. All rights reserved.
