Try
Code:
while true; do echo "$(( 10+i++%46 ))"; done

Code:
#!/bin/bash

counter=10

while true
do
        if [ $counter -eq 56 ]
        then
                counter=10
        fi

        echo $counter

        counter=$(( counter + 1 ))
done

So you might be using a shell not supporting the construct. With bash:
Code:
$ while true; do echo "$(( 10+i++%46 ))"; done
10
11
12
13

54
55
10
