Answer:
If N = 1, and you exclude the portions about added the last four digits of your last four digits, then the answer is 10,000. Someone just figured a way to back into that number.

That means that no matter what number you start with 3 digits or more, you end up with X0,000.

Now to get the last four digits to be your phone number is easy. Just add them twice because you’re already dividing by 2 so you end up with it adding only once. Therefore X+1234 would be X+2468 / 2 would equal the same X1,234.

Sorry I loved Math in school and my ADD makes me think of things in weird round about ways.


So in theory you could take out steps 5 & 6, start with your age and divide by 10,000 and get your age.

Sorry if I took the fun out of this.

It’s simple algebra. I’ve solved it using the information phone number, 555-1212. This is why is works with any 7 digit phone number.

( ( 80x + 1) * 250 + 2y - 250 ) / 2
(20,000x + 250 + 2y - 250) / 2
(20,000x + 2y) / 2
10,000x + y

x = 555
y = 1212

5550000 + 1212 = 555-1212
