What is the 32nd term of the arithmetic sequence where a1 = 13 and a13 = - 59?

We are given with the data in an arithmetic sequence of a1 = 13 and a13 = - 59 and ought to find the 32nd term of the sequence

an = a1 + (n-1) * d

-59 = 13 + (12) * d

d = - 6

an = a1 + (n-1) * d

a32 = 13 + 31 * - 6

a32 = - 173
