Integral Test. we have two arrays [7 -6 9] and [3 4 3], so 7 % 3,3 goes into 7 two times, so the remainder is 1, -6 % 4, 4 goes into 6 one time, so the remainder is 2, 9 % 3, 3 goes into 9 three times, so the remainder is 0. The original test statement was for a series that started at a general n =k n = k and while the proof can be done for that it will be easier if we assume that the series starts at n =1 n = 1. Example.
