Geocache Description:

***** CACHE IS NOT AT THE POSTED COORDINATES *****



Leonardo Fibonacci was born in Pisa, son of Guglielmo Bonaccio (latin Filius-Bonaccii), his father was the director of the custom office of the Republic of Pisa in Bougia-Algeria, responsible for the importation of wax used to make candles in Italy and France (in French the candle is still called “bougie”). In his youth Leonardo followed his father in Algeria where he knew from the Arab traders the “Abacus at the Hindi way”, in which, besides the use of arabic-indian numbers, he learned the use of the ZERO, a notion unknown in the Occidental World. Leonardo recognized immediately the utility of that notion in order to simplify the calculation and composed his famous book “Liber Abaci” which made him the most famous european mathematician in the Middle-Age. It was followed by “De Practica Geometriae” and “Liber Quadratorum”. His fan was the Emperor Frederick II who wanted to meet him personally in Pisa and with him had an important exchange of letters. It is recounted that for the construction of the Castel del Monte Frederick II was inspired by the works of Fibonacci.
In the chapter 12 of his “Liber Abaci” Fibonacci placed this question: How Many Pairs of Rabbits Are Created by One Pair in One Year? ? (Quot paria coniculorum in uno anno ex uno patto germinantur?). To solve this problem Fibonacci introduced his famous series in which each number is the sum of the previous two:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…
Maths:
F(n)=0 for n=0; F(n)=1 for n=1; F(n)=F(n-1)+F(n-2) for n >1
The main property of the series is that the limit of the ratio F(n)/F(n-1) for n to infinity is equal to 1,618033.. that is the golden ratio. Such numbers are found in nature, in the shells of mollusca, in flowers and in pinecones etc..
The cache is NOT at the above coordinates so .....
To find the cache you must use a number of the Fibonacci’s series to answer the question above:

Final Coordinates:
N 48°29.XXX
W 123°32.YYY
Where XXX=NNN-178; YYY=NNN+7
NNN is a number of the Fibonacci’s series. Which one? Only one is Correct, it is your task to find it! Any help? Read the hints.
The cache is an ammo can.


Although you may find more than one answer to this question there is a table that appears in the left margin of the “Liber Abaci” that shows the proof to the correct answer
