Question

How do you find a term in an infinite geometric sequence?

Answer 1

any specific term?

Answer 2

the 101st

Answer 3

you dont!!!!

Answer 4

The question says: Consider the infinite geometric series... e, 1/e, 1/e^3, 1/e^5

Answer 5

I guess he's asking for the geometric serie that goes to the infinite...
I would be \(a \frac{1}{1-r}\)

Answer 6

It*

Answer 7

I already got the ratio but I'm just wondering if there's a specific formula regarding infinite series

Answer 8

lol oh okay thank you (:

Answer 9

*And

Answer 10

wait wait

Answer 11

?

Answer 12

HOLD THE PHONE

Answer 13

lol

Answer 14

question was how do you find a term, not how do you add them up

Answer 15

If you want to find any term, you'll have to use \(\large ar^{n-1}\)

Answer 16

yeah @satellite73 I just noticed it x(

Answer 17

yeah it's how you find it. I know how to find the sum.

Answer 18

Okay okay that other equation makes more sense

Answer 19

where a is the first term, r is the common ratio and n is the term you are looking for.

Answer 20

Okay thanks

Answer 21

@satellite73 , xD and thanks I am half asleep :P
