Consider the sequence. 9, 27, 81, 243, 729,...
Which represents the function used to find any term, z, of the sequence?
O f(3) = 3(3)2-1
O f(x) = 3 + 3.2
O f(x) = 9(3) ---
O f(3) = 9+32

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
