Which sequence is modeled by the graph below?

A.an = 6(−10)n − 1
B.an = 0.6(10)n − 1
C.an = 6(one tenth)n − 1
D.an = one tenth(6)n − 1

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.

rational · Answer

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

anonymous · Answer

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

anonymous · Answer

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

rational · Answer

Yep!

Thank you so much @rational
