C Correct answer
Explanation

The sequence is an arithmetic progression with first term a = 19 and common difference d = 6. The n-th term is a + (n-1)d = 19 + (n-1)6 = 19 + 6n - 6 = 6n + 13.

AI explanation

The given sequence is an arithmetic progression where the first term a is 19 and the common difference d is 6. The formula for the nth term is an = a + (n - 1)d, which simplifies to 19 + 6n - 6, or 6n + 13. The correct nth term is 6n + 13.
