• 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−1Δxn−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.
