The total amount of time spent making hats can be represented by the sequence below.

1.5, 2.25, 3.0, 3.75, ...
Which recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously?

a. f(n + 1) = f(n) + 1.5
b. f(n + 1) = f(n) + 0.75
c. f(n + 1) = f(n)
d. f(n + 1) = f(n)

I would assume it is B, because in the sequence there is a pattern where you're adding .75 to each number.
