Abstract

  This article presents a study of solution to a piecewise linear system of difference equations gif.latex?\inline&space;x_{n+1}&space;=&space;|x_n|-y_n-3 and  gif.latex?\inline&space;y_{n+1}=x_n&space;-&space;|y_n|&space;+&space;1 with initial condition  gif.latex?\inline&space;x_0&space;=&space;0 and gif.latex?\inline&space;y_0&space;\geq&space;1 . After investigations, we found some periodic with period 4 solutions and we proved that solutions with the initial condition are attracted by either one of two period 4 cycles. We explain behavior of solutions to the system via a mathematical inductive statement.
