... than fives, so in fact it suffices to count the fives. That is, we need to count how many fives occur as factors of 1, 2, · · · , n. We have to be careful since some numbers, such as 25, have more than one five. To begin with, we count those numbers that have at least one factor of 5; that is, we co ...

... we get an almost arithmetic sequence, by Lemma 3. Suppose now b <_ -1. Then the integers m satisfying (-mr + s) <_ (~br) form an almost arithmetic sequence. Thus, by Lemma 1,those integers m satisfying (-mr + s) > (-br) = 1 - (br), or equivalently, (mr - s) = 1 - (-mr + s) < (br), form an almost ari ...
