Edgar is getting better at math. On his first quiz he scored 57 points, then he scores 61 and 65 on his next two quizzes.
Which explicit formula can be used to determine Edgars grade on his nth quiz?
A f(n) = 4n + 57 B f(n) = n + 4
C f(n) = 4n + 53 D f(n) = 4(n - 1)
C. f(n) = 4n + 53
(Don't forget 57 was 1st score, need to back up to find the starting point.)
