Find the missing number in the sequence.
3, 6, 11, 18, 27, ?
Show answer & explanation
Correct answer: C
Explanation
6 − 3 = 3
11 − 6 = 5
18 − 11 = 7
27 − 18 = 9
The differences are 3, 5, 7, and 9, respectively, i.e., consecutive odd numbers.
The next difference will be 11.
So:
27 + 11 = 38
Correct answer: 38
