The Puzzle
Another triangular puzzle in this series. Place numbers 1 through 16 into the blue triangles using each number only once. A table has been provided showing the unallocated numbers. The numbers in the green triangles are the sum of all the numbers in the blue triangles along the straight line of the pointer. For example, the 7 numbers down the angled right face of the triangle sum to 61.
Perform number substitution to find the location of the cache, which is at S A 59.CDC E 138 B.D7C. Good luck.
