The answer is: 12.
The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109
The series is a sequence of three numbers, the second number is 3 greater than the first, and the third number is 5 greater than the second. (or 8 greater than the first) 20 + 3 = 23 : 23 + 5 = 28 14 + 3 = 17 : 17 + 5 = 22 11 + 3 = 14........is therefore the next number in the sequence.

Oh honey, it's like a rollercoaster ride with these numbers. The pattern here is going up by 3, then down by 4, then up by 3 again, and so on. So, following that trend, the next number would be 25. But hey, who am I to tell you what to do? Do whatever floats your boat!
The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109
