"Captain," Sophie said, her tone dangerously defiant, "the sequence of numbers you have in your hand happens to be one of the most famous mathematical progressions in history."
The Fibonacci sequence?
The symbolism of the clues meshed too perfectly—the pentacle, The Vitruvian Man, Da Vinci, the goddess, and even the Fibonacci sequence.
And yet they’re all part of the Fibonacci sequence.
"The scrambled Fibonacci sequence is a clue," Langdon said, taking the printout.
He wrote the sequence out of order to tell us to apply the same concept to the text.
It had been Sophie who spotted the Fibonacci sequence, and, no doubt, Sophie who, if given a little more time, would have deciphered the message with no help from Langdon.
Later, she realized the numbers were also a clue as to how to decipher the other lines—a sequence out of order… a numeric anagram.
It’s far too coincidental that this supposedly random account number could be rearranged to form the Fibonacci sequence.
Earlier, Sophie had rearranged this account number into the Fibonacci sequence.
1-1-2-3-5-8-13-21 When the Fibonacci sequence was melded into a single ten-digit number, it became virtually unrecognizable.
When you rotate them to their proper sequence, the tumblers inside align, and the entire cylinder slides apart.
The Fibonacci sequence.
When Sophie had first seen the scrambled Fibonacci sequence on the parquet, she had assumed its sole purpose was to encourage DCPJ to call in their cryptographers and get Sophie involved.
As Langdon loaded his slide projector, he explained that the number PHI was derived from the Fibonacci sequence—a progression famous not only because the sum of adjacent terms equaled the next term, but because the quotients of adjacent terms possessed the astonishing property of approaching the number 1.618—PHI!
This is the Fibonacci sequence," she declared, nodding toward the piece of paper in Fache’s hand.
Obviously there can be no coincidence that all of the numbers Saunière wrote on the floor belong to Fibonacci’s famous sequence.
There are no more uses of "sequential" in the book.
