Answer

Explanation:

Step 1: Calculate the difference between consecutive y-values

$40 - 20 = 20$, $80 - 40 = 40$, $160 - 80 = 80$, $320 - 160 = 160$. Differences are not constant.

Step 2: Calculate the ratio of consecutive y-values

$\frac{40}{20} = 2$, $\frac{80}{40} = 2$, $\frac{160}{80} = 2$, $\frac{320}{160} = 2$. Ratios are constant at 2.

Answer:

They are being multiplied by 2 each time.
