joe was given the recursive formula: f(1) = 3, f(n + 1) = f(n) - 7. to find the second term in the sequence, joe filled in the formula as followed: f(n + 1) = f(n) - 7 then f(n + 1) = f(2) - 7.

he explained since he is finding the second term in the sequence, the n should be replaced by 2.

if he is correct, what are the 2nd, 3rd and 4th terms?

if incorrect, show the correct formula.
