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?
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
No great discovery was ever made without a bold guess.
