Answer 1

What is the equation?

Answer 2

full question: A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100, what is f(6) ?

start with f(1) = 100

to find f(2), plug in n = 1 into the equation

f(n+1) = f(2) = f(1) - 8 = 100 - 8 = 92

repeat with f(3), f(4), etc. until you get to f(6)
