B Correct answer
Explanation

The sequence is an arithmetic progression with first term a = 12 and common difference d = 12. The 8th term is a + (8 - 1)d = 12 + 7 * 12 = 12 + 84 = 96.

AI explanation

The sequence follows a simple arithmetic progression where each term increases by a common difference of 12. To find the 8th term, we use the arithmetic progression formula T_n = a + (n - 1)d. Substituting the values gives the 8th term as 12 + (8 - 1)12 = 12 + 84 = 96.
