The next number in the series should be 15.
The pattern in the series is:
- Starting with 12, the first number is subtracted by 1 to get the second number, which is 11.
- Then, the second number is increased by 2 to get the third number, which is 13.
- The pattern continues by alternating between subtracting 1 and adding 2 to the previous number in the series.
Therefore, following the pattern, the next number in the series should be obtained by adding 2 to the previous number, which is 13, to get 15.
