We noticed that on the outside of this triangle there are ones and they matched, then we noticed that across we had to add that and put it on to the side. We noticed that the answers just doubled. Like 1+1= 2 and 2+2= 4, And then we had to cross out the odd numbers from the triangle. There were more even numbers than there were odd numbers, and we had to fill in the blanks, it’s kind of like finding the sequence in each one.
