What's the pattern 320, 160, 80, 40, ___, ___, ___, show your work!

320, 160, 80, 40, 20, 10, 5

Let's start from the right and go left

5 x 2 = 10

10 x 2 = 20

20 x 2 = 40

40 x 2 = 80

80 x 2 = 160

160 x 2 = 320

All of this is being multiplied by two, but now, let's go from left to right

320/2 = 160

160/2 = 80

80/2 = 40

40/2 = 20

20/2 = 10

10/2 = 5

All of this is being divided by 2

Divided by 2 is the pattern
