Basically the best way to complete this puzzle is starting at M20
Since N to R is five spaces and 14 to 15 is one space apart
From M20
* Five alphabet spaces apart from M would be I or Q
*One number space apart from M would be 19 or 21
Spoilers
Q19 or Q21
I19 or I21
one of the four answers should be right, I recommend saving with ray at the vault .
Hope this helps
