Answer by fcabanski(1391)   (Show Source):
You can put this solution on YOUR website! Substitute n, the number in the sequence, into the formula.
The 4th place, n=4, is 4(5)/2 = 10.
5th place, n=5, is 5(6)/2 = 15.
6th place, n=6, is 6(7)/2 = 21.
7th place, n=7, is 7(8)/2 = 28.
8th place, n=8, is 8(9)/2 = 36.
