Question

What is the 13th term in the arithmetic sequence described by this explicit formula? a(n) = 84 + (n – 1)(–6)

Answer 1

12

Step-by-step explanation:

Just place 13 instead of n.

a(13) = 84 + (13 - 1)(-6)

        = 84 + (12)(-6)

        = 84 + (-72)

        = 84 - 72

        = 12(Answer)
