Arlington Park Series (APS) - A series of caches in small parks in Arlington. Caches are hidden in groups of 5. Each of the first four caches in the group has two clues that are needed to locate the fifth cache. The fifth cache in each of the first four groups contains two clues that are needed to find this cache.
The first cache listing in the series can be found here: APS #01 (Arlington Park Series) - Monroe Park
Note: all caches are in Arlington Parks, and are available during park hours of dawn to dusk. No night caching!
This is the final cache in the series. The Double Bonus Grand Finale. To get here you will need to have found the previous 20 caches in the series and collected clues from: APS #05, APS #10, APS #15 & APS #20. Below you will find a puzzle you need to solve using the clues you collected. The puzzle is not too difficult and makes up only half of the difficulty rating of this cache, the rest of that rating is due to the neccessity of finding 20 other caches to get here.
Here is the puzzle. You should have collected four pairs of clues. You have a Letter and a Number from each cache. The Letter represents its partnered Number in the puzzle below. When you see that Letter just substitute the Number in its place and then sove the math. This will give you the coordinates of this Final cache. Please note that all the clues are whole numbers, there are no decimals.
The cache is at:
N 38° AB.CDE
W 077° 0F.GHJ
(W * X - Y * Z + Z / 4 * W) + ((Y + 7) / 4) = AB.CDE
4 * (Z * W - Z * Y) + X + Y + W + Y / 3 = F.GHJ
