All the numbers at the top must be 20 or more and be a multiple of 4.
The number at the top (n) is made by taking the number at the bottom (k)and using the formula:
4(2k+3)=n
You can find the number at the bottom by dividing the number by 4, take away 3 and then divide the answer by 2. Use the formula:
((n/4)-3)/2=k
