D Correct answer
Explanation

The sequence is arithmetic with a = 8 and d = 6. The n-th term is a + (n-1)d. The difference between the 56th and 48th term is (56-48) * d = 8 * 6 = 48.

AI explanation

The given sequence is an arithmetic progression with a common difference of 6. The formula for the nth term is a + (n - 1)d. The 48th term is 8 + 47(6) = 290, and the 56th term is 8 + 55(6) = 338. The difference between the 56th and 48th terms is 338 - 290, which equals 48.
