Consider the arithmetic sequence presented in the table below.
n
3
64
an
126
3,725
Hint: an = a1 + d(n − 1), where a1 is the first term and d is the common difference.
Part A: What is the first term, a1, of the sequence?
Part B: What is the general term equation, an, for this sequence?
Part C: What is the value of the 13th term of this sequence?
