Well he is making it hard on you i mean you can get the answer all yo do is do 5*4 and then you will get 20 OK well then you do 1*4 easy it =4 well you add them together and you get 24 well you then do 24*2 and you will get 48 which is the answer to 6*8 so your friend left out a step hope you found this helpful <span />
Answer:
a(n) = $0.01*2(n - 1)
Step-by-step explanation:
Let a(n) represent the nth term of this geometric sequence. The common ratio is 2 (which comes from "doubling."
Then the desired formula is a(n) = $0.01*2(n - 1).
Check: Day 1: a(1) = $0.01*2(1 - 1) = $0.01
Day 2: a(2) = $0.01*2(2 -1) = $0.02
Day 3: a(3) = $0.01*2(3 - 1) = $0.04
and so on
... which shows that this formula is valid
