Trying Triangles
These equilateral triangles are trying to test you. There are three numbers for each equal side, and one number in the middle. Your job is to work out how to get to the middle number using the numbers on the sides.

Initially it seems challenging, but with a little trial and error, this one isn’t too bad. Once you have figured out the function and pattern from the three previous triangles, just apply it to the last one, and viola. It’s as easy as that. Share this with your friends and compare scores to see who was tried by the triangles.
