Abstract
The aim of this work is to investigate the global stability, periodic nature, oscillation and the boundedness of solutions of the difference equation
Xn+1= A Pi(k)(i=1) Xn-2i-1/B+C Pi(k-1)(i=1) Xn-2i, n=0,1...
where A, B, C are nonnegative real numbers and l, k are nonnegative integers, l < k. We discuss the existence Of unbounded solutions under certain conditions when l = 0. (C) 2008 Elsevier Ltd. All rights reserved.
