Answer 4

how do i find the ratio? i know i take a term and i divide by the one before but this has points and i don't know how to do it.

Answer 5

look at the y coordinates :
\[6, ~0.6,~ 0.06,~\ldots\]

Answer 6

so the ratio is .1 or 1/10 correct?

Answer 7

and that is C because it's matching with the formula as well where a1= 6 and ratio 1/10 ^ n-1

Answer 8

Yep!

Answer 9

Thank you so much @rational
