Question

Find the most common ratio 72,12,2, 1/3,1/18

Answer 1

1/6

Explanation:

To find the common ratio, you compare a few pairs of consecutive terms, by dividing an element by its predecessor.

12 / 72 = 1/6

2 / 12 = 1 / 6

1/3 / 2 = 1 / 6

The ratio is constant... so that's your common ratio to go from one term to the next.

To go from one term to the next, you have to multiply by 1/6.
