B Correct answer
Explanation

This is an arithmetic progression with first term a=4 and common difference d=3. The 15th term is a + (n-1)d = 4 + (14 * 3) = 4 + 42 = 46.

AI explanation

This sequence is an arithmetic progression where the first term is 4 and the common difference is 3. Using the arithmetic progression formula for the nth term, Tn = a + (n - 1)d, we substitute the known values to get T15 = 4 + (15 - 1)3. Solving 4 + 42 gives the 15th term as 46.
