Difference equations play a key role in analyzing many natural phenomena. Difference equations have many applications in different areas such as economic, biological physics, engineering, ecology, physiology, population dynamics and social sciences. Difference equations could also be used to simplify the dynamical systems represented by differential equations. So there exist rapid interest in investing the dynamics of the solutions of the difference equations. There exist different forms of difference equations including rational, nonlinear, max type and system of difference equations. In this paper, a novel nonlinear difference equation of general order is introduced and some qualitative properties of its solutions are studied. The parameters and the initial conditions of the difference equation are assumed to be positive real numbers. New results concerning the periodicity, semicycles, boundedness and global asymptotically stability are established. We prove that the proposed difference equation has unique positive equilibrium point. The periodic solutions with period two are studied. The semicycle analysis of the proposed difference equation is provided. The boundedness of the solutions is investigated. We give upper and lower bounds on the solutions in terms of the parameters of the proposed difference equation. Moreover, the local and global stability are investigated. Some numerical examples are provided to illustrate our results. The proposed difference equation is of general order, so the obtained results could be used for many difference equations.
