Teynham 10 Puzzle 2 Mystery Cache

Here is the second of the puzzles that will create the Teynham "10"

The cache is not at the above coords, you will need to solve the puzzle below to find the coords for the cache. Good luck

Inside this cache you will find the second half coords for Teynham 10 Puzzle 3

The Teynham 10 is a walk of 5 miles and should take around 2-3 hours depending on find speed. Number 13 should be given the maximum level of stealth and is the meanest seeing as it's no 13!

This second puzzle is a bit simpler and will require just some basic maths to work out.

It is a pyramid, where two numbers next to each other when added will equal the number in the box above those two numbers.

With this you can work both upwards and downwards to get all the four numbers you will require for the coords.

The cache can be found at...
