b does the series converge or diverge?
c. if the series has a sum, find the sum.

Answer 1

first four terms of the series would be:

sum1
sum2
sum3
sum4

Answer 2

the formula for the sum of a geo series can be written as
\[a\frac{1-r^n}{1-r}\]

Answer 3

if r<1 the series converges

Answer 4

how do i find r?

Answer 5

its the thing with the exponent on it ....

Answer 6

okay i got it nevermind............................................................................................................................
