Assuming you just want those integers printed you can do so like this: <?php echo 1; echo 121; echo 12421; echo 1248421; ?>
However, if you're looking for how to print these in some sort of power of 2 in terms of a homework assignment, you can pretty easily find some hints by simple searching the significance of those numbers.
