First off, we can rule out that this is not an arithmetic sequence, as the y values do not have a common difference. Next, let's look at the y values again, and test out the common ratios given. First, let's use 0.6. If it's a common ratio of 5, 3, 1.8, and 1.08, then we can find that out by multiplying it by 5 first. 5 x 0.6 is 3. Then, 3 x 0.6 is 1.8. Finally, 1.8 x 0.6 is 1.08. Therefore, B is correct. The table represents a geometric sequence because the successive y-values have a common ratio of 0.6, since multiplying the values by 0.6 equals the next value down.
