# Mathematician Wanted - Help Identifying Algorithm Being Used

I have a series of 15 digit numbers which are generated from a base algorithm.

For examples, 471103007127719 is broken down by {Prefix}{Sequence}{Master}{Check Digit}

471103007127719

Prefix = a static 5 digit number {47110}

Sequence = a 5 digit number. This is the number that this project will need to predict {30071}

Master = a static 5 digit number {2771}

Check Digit = a 1 digit number calculated from the other numbers

The Sequence number can increment from 1-99999. When I validate the number in my system only SOME of the full 15 digits are valid. It seems that an initial Sequence (ex: 00005) validates. After that there is a gap of ~ 15-25 before another one is successful. For example. The first code in a set is 18.

Then it follows like this:

18,35,51,68,85,101,125,142,159,175,192,209,225,242,266

The difference from one number to the next is

17,17,16,17,17,16,24,17,17,16,17,17,16,17,24

Here is example of testing sequence numbers between 1-50, with only 3 valid 15 digit codes:

47172-00002-2771-2

47172-00018-2771-3

47172-00035-2771-0

This project will require someone to identify the algorithm used to determine the successful sequence.

I will provide:

- the check digit logic (last digit)

- Sample valid codes from a sequence (I have thousands of codes that can be used as a sample set)

I'm willing to look at it. No guarantees, obviously, and of course the project will be paid out if the algorithm is successfully figured out.
