The first term of an arithmetic sequence is 7, and the common difference is 4. What is the 12th term of the sequence?

✓ Correct Answer: Option B

The formula for the nth term of an arithmetic sequence is a_n = a_1 + (n-1)d. Here, a_1 = 7, d = 4, and n = 12. So, a_12 = 7 + (12-1)4 = 7 + (11)4 = 7 + 44 = 51.
