There is a very simple formula. The nth triangular number, T(n) = n*(n+1)/2Here n = 7, so T(7) = 7*8/2 = 28.

One seventh is larger than one eighth. The smaller the number under a 1 in a fraction, the larger that fraction is. Think 1/4, 1/3, 1/2 and you'll see the size of the fraction increasing; the numbers are becoming larger.
Is 63 a triangular number I think it is a triangular number.
013
36.This is the eighth member of the series which can be calculated using the formula(n2 + n) / 2.Where n = 7 we have the triangular number 28 ((49 + 7) / 2).The next number is where n = 8:= (64 + 8) / 2 = 72/2 = 36.
