Abstract

In this paper we investigate the local stability, global stability, and boundedness of solutions of the recursive sequence% \[ x_{n+1}=x_{n-p}\ \left( \frac{2\ x_{n-q}\ +a\ x_{n-r}}{x_{n-q}\ +a\ x_{n-r}}% \right), \] where \(x_{-q+k}\ \neq -a\ x_{-r+k} \) for \( k=0,1,\dots,\min (q,r) , a\in \mathbb{R},\ p ,q, r \geq 0\) with the initial condition \(x_{-p},x_{-p+1} ,\dots, x_{-q},\) \(x_{-q+1} ,\dots, x_{-r},x_{-r+1} ,\dots, x_{-1}\) and \(x_{0}\in (0,\infty )\). Some numerical examples will be given to illustrate our results.
