The formula for a Fibonacci sequence is Xn = Xn−1 + Xn−2. Where Xn, Xn-1, Xn-2 are terms. X is coefficient and n is the variable. Knowing this, see inside how to code and record #'s using Variables and a List.
If you ask for 10 Fibonacci #''s why does the coding subtract 2 from 10, and only repeat the calculations 8 times?
