In this paper, we consider the asymptotic behavior of solutions of the forced nonlinear neutral difference equation $Delta[x(n)-sumpi(n)x(n-k_i)]+sumqj(n)f(x(n-iota_j))=r(n)$ with sign changing coefficients. Some sufficient conditions for every solution of (*) to tend to zero are established. The results extend and improve some known theorems in literature.
