Sufficient conditions are established for oscillation of all solutions of the fourth order difference equation
where is the forward difference operator are real sequences, and is a real-valued continuous function. Also, sufficient conditions are provided which ensure that all non-oscillatory solutions of the equation approach zero as . Examples are inserted to illustrate the results.
