Answer:
f(x+1)=2f(x)
Step-by-step explanation:
Change the fractions to decimals. Once you get the decimals, you divide the second value by the first, because it has already been determined that it's a geometric sequence. You end up getting 2. Plug that into the formula as the common ratio and get the answer.
