Judging by the sequence so far, it appears as though the differences are increasing by 3, while the added numbers are increasing by 6. Therefore, following 17 will be 24 + 6 = 30. Following 30 will be 17 + 3 = 20.

17?
Think it's 30...then 20
The next number in this sequence should be 33.

The pattern in the sequence 11 12 14 17 21 is an increasing sequence where each number is the sum of the previous number and a specific value. In this case, the specific value is increasing by 1 with each subsequent number. So, starting from 11, we add 1 to get 12, then add 2 to get 14, add 3 to get 17, and add 4 to get 21.

The answer depends on where, within the sequence, the missing number should have been.
