We study asymptotic behavior of solutions to the (nonoscillatory) linear difference equation $Delta(r_kDelta y_k)=p_k y_{k+1},$ where $p,r$ are positive sequences defined on ${m,m+1,m+2,dots}subsetZ$. We establish sufficient conditions (in terms of regular variation) for all eventually positive solutions to satisfy certain asymptotic formulae. As a by--product, we obtain regular variation of all these solutions and some other of their properties. Various related problems are discussed and several examples are given.
