Question

Choose the correct explicit formula for the sequence below.

Answer 1

Answer:

an = 3+3(n-1)

Step-by-step explanation:

We are adding 3 each time

6-3 = 3  9-6 = 3

The common difference is 3

The explicit formula for an arithmetic sequence is

an = a1+d(n-1)

The first term is a1 = 3

d =3

an = 3+3(n-1)
