The pattern in this series is that each term is the result of n^2 + n, where n is the position of the term in the series.

For the first term, n=1, so the term is 1^2 + 1 = 2.
For the second term, n=2, so the term is 2^2 + 2 = 6.
For the third term, n=3, so the term is 3^2 + 3 = 12.

Following this pattern, the fourth term, where n=4, should be 4^2 + 4 = 20. However, none of the options given (27, 25, 26, 28) match this result. There seems to be a mistake in the question.
