In this paper, we investigate nonoscillatory solutions of a class of higher order neutral nonlinear difference equations with positive and negative coefficients $Delta^m(x(n)+p(n)x( au(n)))+f_1(n,x(sigma_1(n)))-f_2(n,x(sigma_2(n)))=0,;n{geq}n_0$. Some sufficient conditions for the existence of nonoscillatory solutions are obtained.
