[ale] Sed equivalent for vi command

[Dow Hurst]

If in vi I issue:

:23,23+20 d

I get line 23 up to line 43 deleted.  When I issue at the command line a 
sed command of:

sed -e '23,23+20 d'  inputfile >  outputfile

I get a "Unrecognized command: 23,23+20 d" back from the sed command. 
 Is there a way to do this using sed?
