We are not what you think we are Mystery Cache

The cache is not at the posted coordinates, but this may be a decent spot to abandon the car! The cache coordinates can be found by solving a fairly straightforward number puzzle.

First, you need to find an irrational mathematical constant. It is claimed by some to have mystical, even divine, properties; for others, it's all about the aesthetics.

You will also need a numeric sequence. It's likely that you're already familiar with them both, but you may not have known that they are related. And who says maths is dull?

Use the first eight numbers of the sequence to pick out the required digits (A-H) from the constant.

The cache can be found at:
N 51° 1(A+2).(B-2)(C+6)(D-2)
W 000° 3(E+3).(F-1)(G+1)(H-2)

Congratulations on the FTF to DarenCollins.
