Answer 2

Answer:

31

Step-by-step explanation:

3, 7, 15, ?, 63, 127

The pattern in the series:

Every number is added to consecutive powers of 2. Like,

3 + ($2^{2}$) = 3 + 2×2 = 3 + 4 = 7

7 + ($2^{3}$) = 7 + 2×2×2 = 7 + 8 = 15

15 + ($2^{4}$) = 15 + 2×2×2×2 = 15 + 16 = 31 - The answer

31 + ($2^{5}$) = 31 + 2×2×2×2×2 = 31 + 32 = 63

63 + ($2^{6}$) = 63 + 2×2×2×2×2×2 = 63 + 64 = 127

and so on...

Hope that helps you....☺
