In this paper, the authors investigate the higher-order linear difference equation yn+1=a+a1yn+a2yn-1+…+akyn-k+1,n=0,1,2…, where k is a nonnegative integer, the parametersa,a1,a2,…,ak and the initial conditions y-k+1,y-k+2,…,y0, yo are nonnegative real numbers. The sufficient condition for this equation is obtained here in the paper. Under a sufficient condition, we investigate the convergence and the boundedness of the nonnegative solutions of differential equations.
