In this paper, we study the qualitative behavior of rational recursive sequences $$\begin{aligned} x_{n+1}=\frac{x_{n-17}}{\pm 1\pm x_{n-2}x_{n-5}x_{n-8}x_{n-11}x_{n-14}x_{n-17}}, \quad n \in \mathbb {N}_{0} \end{aligned}$$ where initial conditions are arbitrary nonzero positive real numbers. Also, give numerical examples and solutions graphs some cases difference equations.
