AI Thread Summary
A 14-digit number puzzle requires finding a number that starts with 4, ends with 3, and contains two of each digit from 1 to 7. The digits must be spaced according to specific rules: 7s have seven spaces between them, 6s have six spaces, and so on down to 1s, which have one space between them. A proposed solution involves multiplying 36825889 by 1253777, but the method behind this solution remains unclear. Participants are encouraged to share their approaches, whether through mathematical formulas or trial and error.

Well, I answered this question in a different forum in quite a hurry. So, if you can get it first, hurray for you.

Problem:
You have a 14 digit number. The number begins with 4 and ends with 3.

The trick:
the number has two of each numbers 1-7 in it. The 7's have 7 spaces between them. The 6's have six spaces in between them. The 5's have 5 spaces in between them. So on and so forth, down to the 1's have 1 space between them.

Ready...
Set...
GO!

Eman...please explain how u got it
 
Correctomundo. Like rajesh said, IF you solved this using some mathematical formula, please do tell. If you are like me and just did the trial and error thing, there really is no explanation.

Others feel free to still answer the question.
