You can't use N as a symbol because it has a defined meaning in Mathematica.
If you are new to Mathematica and intend to make much use of it, you would
do well to work through most of Part I in the book, typing in the commands
and familiarizing yourself with the syntax and basic commands.

i have a function
pr[R_] := R*(i+1) -a
and i need to define f as:
f[N_] := pr[pr[pr[pr[R]]]] to N levels deep
how can i do this?
