abstract = {We established positivity of    ∇      f   obtained from a systematic computation of a composition of sequential fractional differences of the function        f   that satisfy certain conditions in a negative lower bound setup. First, we considered the different order sequential fractional differences in which we need a complicated condition. Next, we equalled the order of fractional differences and we saw that a simpler condition will be needed. We illustrated our positivity results for an increasing function of the rising type.}
