Answer:

an = 9+ 6(n-1)

or

an = 6n+3

Step-by-step explanation:

9+ what = 15

15-9 = 6

15+6 = 21

21+6 = 27

We are adding 6 each time  so the common difference is 6

The explicit formula for an arithmetic sequence is

an = a1+d(n-1)  where a1 is the first term and d is the common difference

an = 9+ 6(n-1)

an = 9+6n-6

an = 6n+3
