Hello, KayPee! The numbers in the brackets follow the same pattern: .[2, 6, 24] .[3, 2, 15] .[7, 5, X] Find the value of X. The pattern seems to be: .$\displaystyle [a,\,b,\,3(a+b)]$ Therefore: .$\displaystyle [7,\,5,\,36]$

I can't be certain but I suspect Soroban tried a number of calculations until one worked.
Hello, HallsofIvy! That's exactly what I did.
I have gotten complaints about constantly telling people on this and other boards to try something!
