Abstract.We present here the principal problems of the asymptotic analysis of the sequences. These are: to find a simpler principal part for a divergent sequence or series, to obtain the speed of convergence for a convergent sequence or series by the first iterated limit or by a two sided estimation and finally to obtain an asymptotic expansion. Many of our results are remembered here.
