6 = 8-2
And so on.
Answer:
r is -7
Step-by-step explanation:
(I believe that you mistyped and meant that the fourth term in the sequence should be -686)
The easiest way to find the common ratio is to divide the numbers that are adjacent to each other
![\frac{-14}{2} =-7\\\\\frac{98}{-14} =-7\\\\\frac{-686}{98} =-7](https://tex.z-dn.net/?f=%5Cfrac%7B-14%7D%7B2%7D%20%3D-7%5C%5C%5C%5C%5Cfrac%7B98%7D%7B-14%7D%20%3D-7%5C%5C%5C%5C%5Cfrac%7B-686%7D%7B98%7D%20%3D-7)
As you can see, when we divide a term by its previous term, we get -7 every time. This is our common ratio.
