Abstract
The asymptotic behavior of solutions for the delay difference equation is investigated, where has an asymptotic power series. These equations have been studied for some special cases. This paper analyzes other cases and presents asymptotic expansions of solutions for such higher-order difference equations. Several examples are provided.
