Look at the following sequence.6.12 42.84 299.88 2099.16 if it is a geometric sequence choose the common ratio if it is not a geometric sequence choose "not geometric"a. 7b. not geometricc. 36.72d. 1.43

Hey!
So what I did was I divided 42.84 by 6.12 to see that the answer is 7 and that is an answer choice.
But you should keep checking. 
299.88 / 42.84 = 7
2099.16/299.88 = 7
There is a common ratio and it is 7
A is the answer!
Hope this helps! 

This is a geometric sequence with common ratio 7.

hope it is correct if not i'm srry i tried to
