Which recursive formula can be used to generate the sequence below, where f(1) = 6 and n ≥ 1?

6, 1, –4, –9, –14, …

f (n + 1) = f(n) + 5
f (n + 1) = f(n) – 5
f (n) = f(n + 1 ) – 5
f (n + 1) = –5f(n)

@eekv

notice how the sequence starts with 6 and decreases by 5 each time

looking at the formulas, which one do you think represents a sequence that starts with 6, and decreases by 5?
