Answer 4

Thanks

Answer 5

Wait

Answer 6

np! :)

Answer 7

How does 3/5^n + 3/n diverge?

Answer 8

because coefficient of top and bottom are 1

Answer 9

3?

Answer 10

I meant not equal to 1

Answer 11

I still do not understand... could you explain further please? :)

Answer 12

sure for instance if the an= 2x+whocare/2x+whocare the only thing you look at is the coefficient

Answer 13

couldn't we just say it is the infinite sum of 1/5^n + 1/n times 3?

Answer 14

2x/2x =1 which means converge if not it is diverge

Answer 15

wait would 1/5^n be diverging?

Answer 16

I assume it is

Answer 17

Do you possibly know how or why? :)

Answer 18

I just checked and apparently 1/ 5^n does converge.

Answer 19

becuase 1 does not have variable but the denominator which is 5^n power which is any number

Answer 20

ok ty

Answer 21

aha it is not converge
