If you just simply cannot figure it out, then don’t worry because we will offer a full explanation as to how you get the last number below.

The last number can be calculated in two different ways.

Method 1: To get the last number, ad the numbers on the right side of the equation, and then multiply that sum by three.  By this logic, 1+5=6, which indeed gives you 18.  2+10=12, which when multiplied by 3 does give you 36, and same with 54.  So 4+20=24, multiplied by 3 gives you 72.
