Our approach is based on studying the considered equation as a system of a four-dimensional difference system. The sufficient conditions under which the considered equation has no quickly oscillatory solutions are given. Finally, the sufficient conditions under which the equation is almost oscillatory are presented.enfourth-order difference equationneutral typequickly oscillatory solutionsalmost oscillatoryArtykuł
