Nola Ray · Answer 2

Answer: it is an Arithmetic sequence the formula is f (n) = 7+5• (n-1)

Step-by-step explanation:

the first term is the price of a single shirt which is $7 the common difference is the price of any additional shirt, which is $5 therefore and explicit frma for the sequence would be f (n) = 7+5• (n-1)
