Find the missing number: 1, 3, 7, 15, 31, 63, ______?
Explanation
The pattern of the sequence is obtained by adding 2, then 4, then 8, then 16, and so on (doubling the previous addition).Therefore, the next number in the sequence would be:
1 + 2 = 3
3 + 4 = 7
7 + 8 = 15
15 + 16 = 31
31 + 32 = 63
63 + 64 = 127
So, the correct answer is: 127
