Given:

2n + 5

n = 1 to n = 12

2 (1) + 5 = 2 + 5 = 7

2 (2) + 5 = 4 + 5 = 9

2 (3) + 5 = 6 + 5 = 11

2 (4) + 5 = 8 + 5 = 13

2 (5) + 5 = 10 + 5 = 15

2 (6) + 5 = 12 + 5 = 17

2 (7) + 5 = 14 + 5 = 19

2 (8) + 5 = 16 + 5 = 21

2 (9) + 5 = 18 + 5 = 23

2 (10) + 5 = 20 + 5 = 25

2 (11) + 5 = 22 + 5 = 27

2 (12) + 5 = 24 + 5 = 29

Sum: 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25 + 27 + 29 = 216
