A simple puzzle about triangles (ok they're hexagons in the picture, but they form a triangle)
Just work out the numbers in the appropriate coloured hexagons and add them up, then substitute them back into the formula to get the co-ordinates.
The cache can actually be found a few metres north of the calculated co-ords, for reasons which should be obvious when you work it out.
Basic, really... or is it?
N50 5x.xxx where x=sum of red hexagons
W001 0y.yyy where y=sum of blue hexagons
Update 11 Jun 2025 - Once you have done the above add .010 to the N and add .002 to the W
