We consider the following nonlinear difference equation: xn+1=f(pn,xnm,xnt(k+1)+1), n=0,1,2,, where m{0,1,2,} and k,t{1,2,} with 0m<t(k+1)1, the initial values xt(k+1)+1,xt(k+1)+2,,x0(0,+), and {pn}n=0 is a positive sequence of the period k+1. We give sufficient conditions under which every positive solution of this equation tends to the period k+1 solution.
