{\textbf {Abstract:}} The global asymptotic stability of the unique
positive equilibrium point and the rate of convergence of positive
solutions of the system of two recursive sequences has been studied recently.
Here we generalize this study to the system of $p$ recursive sequences $x_{n+1}^{(j)}=A+(x_{n-m}^{(j+1)mod(p)}/x_{n}^{(j+1)mod(p)})$, $n=0,1,\ldots,$
$m,p\in \mathbb{N}$, where $A\in(0,+\infty)$, $x_{-i}^{(j)}$ are arbitrary positive numbers for $i=1,2,\ldots,m$ and
$j=1,2,\ldots,p.$ We also give some numerical examples  to demonstrate the effectiveness of
the results obtained.

{\textbf {Keywords:}} System of
 fractional difference equations, periodic solutions, Boundedness, the asymptotic behavior, Stability. \\
