sam (.sam.):

\[r=\frac{n_2}{n_1}\]

OpenStudy (anonymous):

n2=?

sam (.sam.):

\[r=\frac{n_2}{n_1}=\frac{n_3}{n_2}=\frac{n_4}{n_3}...\]

sam (.sam.):

\(n_1=-3\) \(n_2=6\) \(n_3=-12\) \(n_4=24\)

OpenStudy (anonymous):

r=6/-3

sam (.sam.):

Yes

OpenStudy (anonymous):

r=6/-3 r= -12/6 r=24/-12?

OpenStudy (anonymous):

So what do I find next?

sam (.sam.):

Yeah just find r? that's the r

sam (.sam.):

6 divided by -3 is

OpenStudy (anonymous):

-2

sam (.sam.):
