deleting atoms which their (Z position + their Radius) is greater than a number

Dear all,
I want to delete atoms which their (Z position + their Radius) is greater than a number.
I used property/atom to make an array for (Z position + their Radius).
But I couldn't figure out how to make a group of atoms which their (Z position + their Radius) is greater than for example 100.
which command or combination of commands should I use?

you can select atoms for a group based on atom style variables. for
that please have a look at:
