Question

a_n=(3^(n+1))/(2^n)

Answer 1

\[a _{n}=3^{n+1}/2^{n}\]

Answer 2

wat shuld we do?

Answer 3

my bad
is it convergent

Answer 4

Do u know what Convergency mean?

Answer 5

Or what a divergency mean?

Answer 6

see if you can show that it's a cauchy sequence

Answer 7

yeah, the n in the exponents are throwing me off

Answer 8

It is not convergent!

Answer 9

yup it is not

Answer 10

what test did you use in figuring that out

Answer 11

it's a geometric series where |x| > 1

Answer 12

I said That its not divegent using P series test!

Answer 13

ok to sum it all up u can use those rules (p) and geometric if it is a sequence and a series

Answer 14

\[a_n=3\left(3\over2\right)^n\]
never converges

Answer 15

so can you use the p series rules with sequences as well

Answer 16

yeah!

Answer 17

In maths, U can use anything anywhere as long as it satisfies them!
