Abstract In this paper, first we prove some new refinements of discrete weighted inequalities with negative powers on finite intervals.Next, by employing these inequalities, we Graters prove that the self-improving property (backward propagation property) of the weighted discrete Muckenhoupt classes holds.The main results give exact values of the l
