Solving Difference Equations by Forward Difference Operator Method

ABSTRACT In this paper a forward difference operator method was used to solve a set of difference equations. We also find the particular solution of the nonhomogeneous difference equations with constant coefficients. In this case, a new operator call the forward difference operator ∆r,s, defined as ∆r,s yn = r yn+1 - s yn, was introduced. Some of the properties of this new operator were also investigated.
