C Correct answer
Explanation

The differences between consecutive terms are: 5-2=3, 9-5=4, x-9=5, 20-x=6, 27-20=7. The pattern is +3, +4, +5, +6, +7. So 9+5 = 14.

AI explanation

The pattern in this series involves adding consecutive odd numbers starting from 3. We add 3 to the first term 2 to get 5, add 4 to 5 to get 9, and add 5 to 9 to get the missing term 14. We can verify this by adding 6 to 14 to get 20 and adding 7 to 20 to get the final term 27. The missing term is 14.
