The 18th Fibonacci number result is 4181. I
discovered 4181 to be the sum of the Greek (3168) and
prime number (1013) gematrias of 'LORD JESUS CHRIST'.
The 17th Fibonacci result is 2584. In the range of: 1 to
23,145 Old Testament verses there are 2584 prime numbers
(including Unity).
From http://www.biblegematria.com/the-golden-ratio.html note
the appearance of 5778 as the 18th position:
A cousin of
the Fibonacci numbers is a sequence obtained by a similar
technique, but beginning with the numbers 2, 1, 3, 4, 7...
etc. Numbers in this series are called Lucas
numbers (named after another mathematician) which
also display interesting properties.
Using the same method outlined above, Lucas numbers can also be used to approximate phi. It's true that the golden ratio can be approximated using many more number sequences, but the most accurate come from the Fibonacci and Lucas number series. For example, the number 5778 approximates phi to within 0.000000175% (5778 / 3571 = 1.1.61803416...).
