Most likely this is randomized in such a way that when he generates the next number it will be vastly different from if he did it, say, 1 second earlier. Or he's using a very large polynomial function and using the last digits of a number generated. Unless you have thousands of numbers, it will be very difficult to figure out.

You could do quadratic regression on these 3, cubic when you have the next number, and so on, but I seriously doubt that would get you anywhere.

WHY? Are you the "manager"?
Can you post something clearer, in correct English? Thank you.
