Is there a way to make the following script more efficient using a single loop? I want n to be 1 through 254 excluding 10 and 225. How would I go about doing that?

#!/usr/local/bin/bash
nr="172.16.2."
n=1
msg="Adding static route for: "
while [ $n -le 9 ]
do
        /bin/echo $msg$nr$n
        /sbin/route add $nr$n -interface tun0
        n=$((n+1))
done
n=11
while [ $n -le 224 ]
do
        /bin/echo $msg$nr$n
        /sbin/route add $nr$n -interface tun0
        n=$((n+1))
done
n=232
while [ $n -le 254 ]
do
        /bin/echo $msg$nr$n
        /sbin/route add $nr$n -interface tun0
        n=$((n+1))
done
