Consider the arithmetic sequence presented in the table below. n 3, 64
an 126 3,725
Hint: an = a1 + (n - 1), where a is the first term and d is the common difference.

Part A: What is the first term, a1, of the sequence? (2 points)

Part B: What is the general term equation, an, for this sequence? (1 point)

Part C: What is the value of the 13th term of this sequence? (1 point)
