This is my forth hide and my first puzzler. I was presented this sequence a number of years ago and I have to admit I gave up before solving it. Once I was told the answer I kicked myself and have remembered it ever since. Hope you enjoy it.
Solve the sequence to find the coordinates and the cache.
? ? ? ? ? ? ? ? ? ?
The next sequence contains 10 digits. Each digit is represented by these corresponding letters:
A B C D E F G H I J
Solve the sequence, then use the formulas below to get the latitude and longitude for the hide location.
North (A+B+G) (A+C+F) deg (C+D+E) (G+J) dot (F*J) (E+F+G) (E+J)
West (A-A) ((D*(E+G)) (A+A) deg (F+G+H) (G*J) dot (F+G+H+I) (A+B+H) (G*J)
I'll see how tricky this one is before posting any hints. You can check your answers at GeoCheck.org. Here's the link and the tally.
