I don't think brace expansion will do what you want here, though I 
Could Be Wrong.  Try this:

for i in audio video input dialout plugdev tty ; do
   sudo adduser pi $i
   done

...the "for i in A B C ; do ... done" loop in bash is really useful and 
really easy.  Works with any list of space-separated items, so if you 
want to do something 10 times, "for i in `seq 1 10` ; do ... done" and 
Bob's your uncle.
