Abstract: The main objective of this paper is to study the boundedness character, the periodicity character, the convergence and the global stability of positive solutions of the difference equation <br> $$x_{n+1}= \frac{α0x_{n} + α1x_{n−l} + α2x_{n−m} + α3x_{n−k}}{β0x_{n} + β1x_{n−l} + β2x_{n−m} + β3x_{n−k}}$$, $$n = 0, 1, 2, · · ·$$ <br> where the coefficients $$α_{i}, β_{i} ∈ (0, ∞)$$ for $$i = 0, 1, 2, 3,$$ and $$l, m, k$$ are positive integers. The initial conditions $$x−k,...,x−m,...,x−l , ...,x−1, x0$$ are arbitrary positive real numbers such that $$ l < m < k$$. Some numerical experiments are presented.
