If you design a booklet, make normal following pages, as it should be done:
Let the printer do the imposing as you have not the needed know-how to do it correctly.
Set up your document as facing pages and EXPORT as PDF according the settings given from your printer.
Set your auto number on your master on its own layer on top of all other layers.
Anything else is crasp.
That's not a good idea.
The imposition of pages should not be done in InDesign.
Your InDesign layout should always reflect the order of pages in reading order.
Imposition is an extra step after creating a PDF with pages from 1 to 100.
Usually done by the print shop. And with special software, that accounts for various parameters. Sheet size, binding, paper thickness, …
If you want to print that on your own laser printer, you could use InDesign's Print to Booklet function.
Or you can do it from Acrobat Pro or Acrobat DC using a similar feature.
Or your printer driver has a similar feature.
