Consider the arithmetic sequence presented in the table below.

n 5 71
an 74 1,460

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?
