Given an arithmetic sequence in the table below, create the explicit formula and list any restrictions to the domain. (2 points) n an 1 40 2 47 3 54 an = 40 + 7(n − 1) where n ≥ 40 an = 40 + 7(n − 1) where n ≥ 1 an = 40 − 7(n − 1) where n ≥ 40 an = 40 − 7(n − 1) where n ≥ 1
Accepted Solution
A:
an = 40 +7(n-1) where n is greater than or equal to 1
