 Form and Periodicity of Solutions of Some Systems of Higher-Order Difference Equations PP: 79-84 doi:10.18576/msl/050111 Author(s) Abstract This paper deal with form, the periodicity and the stability of the solutions of the systems of difference equations $$x_{n+1}=\frac{1}{1- y_{n-k}},\,y_{n+1}=\frac{1}{ 1- x_{n-k}}\label{eq2}$$ where $\mathbb{N}_{0}=\mathbb{N}\cup \left\{0\right\}$ and the initial conditions $x_{-k}$, $x_{-k+1},\ldots$, $x_{0}$, $y_{-k}$, $y_{-k+1},\ldots$, $y_{0}$ are non zero real numbers.
