Notice the lowest number = the sum of 2 and 7.
Notice that the middle number = the sum of the lowest number and 11.
Notice that the top number = sum of middle number and 3.
So top number = middle number + 3
= lowest number + 11 + 3
= 2 + 7 + 11 + 3
= 23.
And that's why you don't actually need to find the other two numbers. The top number is just the sum of all the known numbers below it
