Answer 1

that is just a geometric series
is it not?

Answer 2

So a =1 and r= 1/sqrt{3} ^ n?

Answer 3

1/sqrt{3}?

Answer 4

\[\frac{1}{(\sqrt{3})^n}=(\frac{1}{\sqrt{3}})^n\]

Answer 5

Okay!!

Answer 6

so r=1/sqrt(3)

Answer 7

How did you know it was a geometric series?

Answer 8

What is a? Is it just 1?

Answer 9

yep

Answer 10

Oh ok

Answer 11

\[\frac{1}{(\sqrt{3})^n}=(\frac{1}{\sqrt{3}})^n=1 \cdot (\frac{1}{\sqrt{3}})^n\]
