using limit comparison test

OpenStudy (anonymous):

im pretty sure im going to be using the limit comparison test but his just looks divergent from the start.

OpenStudy (anonymous):

first use the eyeball test then use the limit comparison test to verify your answer

OpenStudy (anonymous):

\[\sum_{n=1}^{\infty} \frac{ 4^{n+1} }{ 3^{n}-2}\]

OpenStudy (anonymous):

looks like geometric with \(r=\frac{4}{3}\) so diverges guess you could compare it to that one

OpenStudy (anonymous):

clear or no?

OpenStudy (anonymous):

yeah it seems to be divergent as well because 0<original< 4/3

OpenStudy (anonymous):

i mean 0<4/3<original*

OpenStudy (anonymous):

yeah actually you can use the straight up comparison test since \(3^n-2<3^{n+1}\)you have \[\frac{4^{n+1}}{3^n-2}>(\frac{4}{3})^{n+1}\]
