1. Introduction
Recently, the asymptotic properties of the solutions of second order differential equations [1] [2] difference equ-
ations of the type (E) and/or related equations have been investigated by many authors, for example see, [3]-[19]
and the references cited there in. Following this trend, we investigate the existence of these six types of solutions
of the Equation (E) showing the necessary and/or sufficient conditions can be obtained for the existence of those
solutions. For the general backward on difference equations, the reader is referred to the monographs [20]-[24].
In 1996, PJY Wang and R.P. Agarwal [25] considered the quasilinear equation
