Answer:

aₙ=aₙ₋₁+7

Explanation:

The general formula for the recursive form of an arithmetic sequence is

aₙ = aₙ₋₁ + d, meaning "the next term equals the previous term plus the common difference".

Find the common difference by subtracting the 1st term from the 2nd, and verify by subtracting the 2nd from the 3rd, 3rd from the 4th and so on.
