Plz help...I'll be ur fan................
Blake goes running for 10 minutes on Sunday. Every day he doubles his running time. If he continues this pattern, how many minutes will he run on the 7th day?
I'm confused about which formula I should use:
f(n) = f(1) • r^(n−1) or an = a1 • r^(n−1)
are these even the correct formulas for this question????
