The answer is: 12.
The pattern in this series involves alternating between a single number increase and a jump of multiple numbers. The series starts with 2, then increases by 1 to 3, jumps by 7 to 10, increases by 2 to 12, increases by 1 to 13, jumps by 7 to 20, and so on. Following this pattern, the next number in the series would be 40.
20? Just a guess
29, assuming it is an algebraically reclusive sequence.
