(a) 1 + 3 + 5 + 7 = 16
1 + 3 + 5 + 7 + 9 = 25
(b) 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25 + 27 + 29 = 225
(c) 1/2 + 3/2 + 5/2 + 7/2 + 9/2 + 11/2 + 13/2 + 15/2 + 17/2 + 19/2 + 21/2 + 23/2 + 25/2 + 27/2 + 29/2
= (1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25 + 27 + 29) / 2
= 225/2
= 112 1/2
