So vague.

I'm going to assume you started with something like this:

case $input in
  [2-6]) echo "yeah, that's good";;
esac

and you maybe figured out how to extend it to something like this:

case $input in
  [2-68-9]) echo "yeah, that's good, screw 7";;
esac

but then you struggled with how to extend it to something like "3 to 5,
or 9 to 13" because you can't express that with a single glob-type
pattern.

Fear not!  You can just use more than one pattern.

case $input in
  [3-5]|9|1[0-3]) echo "yeah, that's good";;
esac
