What is the explicit rule for the sequence?

Answer:

an=12−1.5n

Step-by-step explanation:

The first term is 10.5.

The common difference is ...

9 - 10.5 = -1.5

The n-th term can be described by ...

an = a1 +d(n -1)

an = 10.5 -1.5(n -1) = 10.5 -1.5n +1.5 . . . . eliminate parentheses

an = 12 -1.5n
