Answer 2

(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
