How do I make 3 different transclucent layers all equal opacity?

[CDriv3]

I have 3 different layers, each varying in opacity. How can I blend them all equally?

 

Am I just dumb?

 

85op/85op/85op does not work.

85/175/255 does not work.

what is my dumbass missing?

 

Also, what order do i merge them? middle->bottom, top->middle/bottom; or top->middle, top/middle->bottom?

Not sure if this will do what you want, but try it:

 

Top layer  Opacity  85
Mid layer  Opacity 128
Base layer Opacity 255

 

Regarding merging the layers, when the image 
looks the way you want it to look, then:

Merge Mid layer down into Base, then merge Top layer down. 
or
Image > Flatten

The pattern, in case it's not implicit from @ardneh's comment, is that each layer's opacity is divided by its distance from the bottom, starting at 1.

 

So for five layers:

Top:   Opacity 51 = 255/5

Next: Opacity 64 = 255/4 (rounded)

Next: Opacity 85 = 255/3

Next: Opacity 128 = 255/2 (rounded)

Base: Opacity 255 = 255/1
