Question

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

Answer 1

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

Answer 2

Answer:

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

Step-by-step explanation:

320, 160, 80, 40, ___, ___, ___,

To find out the pattern we look at the number how they are decreasing

first number is 320 and second number is 160

$\frac{160}{320} = \frac{1}{2}$

$\frac{80}{160} = \frac{1}{2}$

$\frac{40}{80} = \frac{1}{2}$

Common ratio is 1/2

To get next term we multiply by 1/2

$40 \cdot \frac{1}{2} = 20$

$20 \cdot \frac{1}{2} = 10$

$10 \cdot \frac{1}{2} =5$

Next three terms are 20,10 and 5
