Whats your question and choices? :)
Answer:
36
Step-by-step explanation:
N = 6
S = 0 n = 1
2(1) - 1 = 1
S = 0 + 1 = 1
n = n + 1
n = 1 + 1
n = 2
S = 1 n = 2
2(2) - 1 = 3
S = 1 + 3 = 4
n = n + 1
n = 2 + 1
n = 3
S = 4 n = 3
2(3) - 1 = 5
S = 4 + 5 = 9
n = n + 1
n = 3 + 1
n = 4
S = 9 n = 4
2(4) - 1 = 7
S = 9 + 7 = 16
n = n + 1
n = 4 + 1
n = 5
S = 16 n = 5
2(5) - 1 = 9
S = 16 + 9 = 25
n = n + 1
n = 5 + 1
n = 6
S = 25 n = 6
2(6) - 1 = 11
S = 25 + 11 = 36
n = n + 1
n = 6 + 1
n = 7 > N
