was playing an online game and came across this triangle..
numbers looked strange to me
8 12 13
5 6 14 9
2 3 10 11 15
any ideas how to crack this one? any patterns?
Welcome to the forum. What do they want? The next row? One particular number?
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
