Question

True or False The series is divergent?

Answer 1

\[\sum_{n=0}^{\infty} \frac{20}{10^n}\]

Answer 2

now I was curious if I could do this.\[\sum_{n=0}^{\infty} 20 (\frac{1}{10})^n\] to make it a geo series?

Answer 3

Calc 2.

Answer 4

Wuh....?

Answer 5

I guess I'm continue from here then..

1/10 < 1 so

A/(1-r)

Answer 6

20/(10/10 - 1/10)

20 * 10/9 = 200/9 :)
