The question is:
type an equation for the following pattern

the chart is
x. y

1. | 16
2. | 8
3. | 4
4. | 2
5. | 1

the equation to put the numbers in is:
y= __ )

Y equals thirty two divided by two to the x power
y=32/(2^x)
I don't know how to put this into the form you needed, because I don't think that is possible, but perhaps the first blank is 32 the second is 1 and the third is 2 to the power of x
