Abstract In this paper we are concerned with some new criteria for the oscillation and nonoscillation of the second-order nonhomogeneous linear difference equations of the form Δ(cn − 1 Δxn − 1) + qnxn = fn,n = 1, 2,…, where {cn}, {fn}, and {qn} are real sequences,cn > 0 forn ≥ 0, and Δxn = xn + 1 − xnis the forward difference operator. The discrete analogs of some of the known results in the continuous case are presented.
