Oh wait...

Answer 3

You have to take the square root of that, because the ratio of 4/3 to 12 is spread out over 2 terms. (Does that make any sense?)
First, what is 4/3 divided by 12?

Answer 4

no it doesnt make sennse

Answer 5

What is 4/3 divided by 12, first of all?

Answer 6

\[an = ar ^{n-1}\]

so we know a2

12 = a(r)^1

we know 4 the term

4/3 = a(r)^3

so here's what we d\[\frac{ 4 }{ 3 \times 12 } = r ^{3 -1}\]

Answer 7

so now we know that r = 2/6

Answer 8

do you simplify 2/6?

Answer 9

1/3 DONE!
