For ex., looking at 426, the 4 and the 6 diverge into two different directions, so lets look at this for now. The reason is because there is a missing number in the sequence of numbers, 5, so we take the missing number 5 and what number is in the middle, 2, so we have 25X now. How do we get the last number, we take and add the first and last number to get 254 and 256.
I just gave one way of looking at the numbers but now let's do a slightly fancier ex.
For ex. you have 436 come in, you have EOE, so now we are going to look for 2O and 1E. We know that the missing number of the divergence is a 5 but is that the number, we are really looking for. Maybe a 7 or 9 will come in, but one thing for sure we know, 2 odds will come in, so we put the number with the middle number, such as 734 or 736.
Another ex. 739, missing 8, put 8 with 3 and add the 1st and last number and you got 387. When all odd, we just add one even or go all even.
What to do when the divergence is side by side will discuss later.
