When we distribute, we multiply the number outside of the parenthesis to every number inside the parenthesis.
So we have:
Answer:
I cant see the whole question...
As we can see it's a geometric progression.
q = a2/a1
q = 1/3
so,
an = a1 . q^(n - 1)
an = 3 . (1/3)^(n - 1)
The one which matches is f(n) = 3 . (1/3)^(n - 1)
