C Correct answer
Explanation

The sequence consists of prime numbers: 13, 17, 19, 23, 31. The number 27 is not prime (it is 3^3), so it is the wrong term.

AI explanation

The sequence is intended to list consecutive prime numbers starting from 13. Since 27 is divisible by 3 and 9, it is a composite number and not prime. Therefore, 27 is the wrong term in the sequence.
