DrRocket Posted January 3, 2012 Share Posted January 3, 2012 what is the limit of a^n as n reaches infinity if a <-1, and WHY ? I asssume that you are working over the set of real numbers, and that n is a natural number. The sequence that you propose has no limit. In fact the absolute value grows without bound, and the sign oscillates depending on whether n is even or odd. Link to comment Share on other sites More sharing options...
