Explanation

This is an arithmetic progression with a=3 and d=4. The 17th term is a + (n-1)d = 3 + (16 * 4) = 3 + 64 = 67.

AI explanation

The given arithmetic series has a first term a = 3 and a common difference d = 4. To find the 17th term, use the nth term formula T_n = a + (n - 1)d. Substituting the values gives T_17 = 3 + (17 - 1)4, which simplifies to 3 + 64 = 67.
