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.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
