C Correct answer
Explanation

The sequence is an arithmetic progression with first term a=3 and common difference d=2. The n-th term is a + (n-1)d. For n=7, term = 3 + (7-1)*2 = 3 + 12 = 15.

AI explanation

The sequence follows the arithmetic progression formula T_n = a + (n - 1)d. The first term (a) is 3 and the common difference (d) is 2. To find the seventh term, calculate 3 + (7 - 1)2 = 15.
