If you take the middle number of the five consectutive numbers for a Magic V and multiply it by 3 it will give you the middle number of the range of totals you could get for that magic V. There are only 3 consecutive totals for each V depending on which number is on the bottom of the V.
For example, for numbers 12-16, the middle number is 14. 14 times 3 is 42 so the range of totals is 41 to 43.
OR
Middle number of consectutive numbers is y
Middle number of the range of total is z
3y = z
