Abstract
The main goal of this paper, is to obtain the forms of the solutions of the following nonlinear fifteenth-order difference equations
x(n+1) = x(n-14)/+/- 1 +/- x(n-2)x(n-5)-x(n-8)x(n-11)x(n-14), n = 0,1,2, ...,
where the initial conditions x(-14), x(-13), ..., x(0) are arbitrary real numbers. Moreover, we investigate stability, boundedness, oscillation and the periodic character of these solutions. Finally, we confirm the results with some numerical examples and graphs by using Matlab program.
