Geocache Description:


To log this cache you must have met the requirements. The D/T is based on the qualifications to meet the challenge. The actual D/T would be 1.5/1.5. 

The Fibonacci Challenge

The cache IS hidden at the posted coordinates, but you must qualify!

In mathematics, the Fibonacci numbers form a fascinating sequence you have probably seen or heard of before, the Fibonacci sequence, in which each number is the sum of the two preceding ones.  This string of numbers begins with 1 and 1 and then continues as shown below;

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711 etc.

The Fibonacci sequence is named after Leonardo of Pisa, a.k.a, Fibonacci, who is credited with introducing the number sequence to Western European mathematics in 1202. As you follow the growth of the Fibonacci Sequence, the ratios of consecutive terms approach a certain irrational number that has been called, Phi, or the Golden Number. This number is amazingly tied to many natural phenomena in nature such as the branching of trees, leaves on a stem, the flowers of an artichoke, the fruit sprouts of a pineapple and even the layering of a pine cone’s bracts.  Relationships to this sequence can also be seen in other places as well such as computer programming architecture, DNA, music, mathematics, even Geocaching!

So, in order to qualify for this cache, you will need to look within your own cache finding statistics to determine how closely tied to the Fibonacci sequence you are.  You will need to list out each type of cache you’ve found and tie that to one of the Fibonacci numbers, just like the example shown below, listing the quantity of them you have.  Starting with 1, you will need to identify a type of cache you have found and then list the amount of them found which must exceed the Fibonacci number.  You may not skip a Fibonacci Number in the sequence, and you continue listing as many types as you can so that your number of finds is at least as large as the Fibonacci Number in the sequence. The number of rows you are able to complete is the level you have achieved in the Fibonacci Challenge. To qualify for this challenge, you need to achieve at least Level 10.  I know it’s a bit confusing at first, but check out this example;

 

Here's an example of a CORRECT posting for someone who has met Level 12:

Fib# - Cache Type - Number of My Finds
1 - Project APE - 1
1 - GPS Adventures Exhibit - 1
2 - Mega Event - 2
3 - Lost & Found Event - 4
5 - CITO - 7
8 - Wherigo - 8
13 - Letterbox - 14
21 - Earthcaches - 40
34 - Multi - 83
55 - Virtual - 90
89 - Unknown - 168
144 - Traditional - 3433

Here's an example of an INCORRECT listing - the count of Earthcache finds isn't enough to continue the sequence:

1 - CITO - 1
1 - Wherigo - 3
2 - Letterbox - 6
3 - Mega Event - 6
5 - Event - 10
8 - Multi - 11
13 - Earthcache - 12
21 - Virtual - 25
34 - Unknown - 75
55 - Traditional – 2012

Logging Requirements:

1. You must have found this cache, signed its log book, and rehidden it in its hiding location. (Note: The difficulty and terrain rating are based upon the challenge, not the cache hide itself.)

2. Your list of Geocaches Found (from geocaches tab on user profile) posted must include at least 10 different types of geocaches. Please include in your log the length of the Fibonacci sequence (level) you were able to complete. Paste the output from the challenge checker below.

3. Each type of Geocache Found can only be used once in the sequence. Allowable types that you may use for this challenge are the types listed here on the geocaching website in the list shown.  

4. If you have found this cache and signed the log, you may log a note stating that you've found the cache, regardless of whether you've met the requirements. This allows you to convert your log into a find once you meet the requirements by posting your qualifying find counts as described here.
