Im thinking of a 10 digit number, were every number is different. The number created by taking numbers from the beginning is divisble by the number of numbers taken from the beginning. (GOT IT)
EXAMPLE (Not the solution)
1234567890
1 is divisble by 1
12 is divisble by 2
123 is divisible by 3
1234 is NOT divisible by 4.
A 10 digit number needs to be created so it will work for every number 1-10
Once Solution is found assign a letter to each digit starting with A for the first digit
Final: N 40o 2D.IBJ W 074o 2E.IDC
Enjoy!
