The next number is 2.
11
Since each number is one less than the one before it, the next number would be 8.
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.
