Well this is a bit of a detour from the other suggestions however since you
haven't gotten a successful solution yet how about
for ($i=1; $i<=$num_pages; $i++) {
$number = ($i * 20) + 1;
// print stuff here
}
The results would be $number = 21 on first run, then 41, then 61 etc (which
I believe is what you are looking for). Note the parenthesis in the $number
line are not needed however I typically code with them as it makes it easier
to understand the code with less though =)
