# PTIJ: Fibonacci Numbers - Mi Yodeya? [closed]

## מספר פיבונצ'י - מי יודע

From Wikipedia:

In mathematics, the Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and characterized by the fact that every number after the first two is the sum of the two preceding ones. Such as:

1,1,2,3,5,8,13,21,34...

The first two numbers are defined as 1 and 1.

In the spirit of the song "Echad - mi yodeya", please post interesting and significant Jewish facts about Fibonacci numbers. I was able to find something interesting about the first two numbers, but nothing Jewishly related regarding the number sequence. Maybe you can add things up and come up with something ;-)

Please, no lazy gematria about these numbers. I'm looking for something clever.

• I'm not sure this qualifies as Purim Torah under the policy – Double AA Feb 19 '18 at 23:30
• @DoubleAA We have one last year regarding irrational numbers. How is this different? – DanF Feb 20 '18 at 0:08
• Hmm let's see - the first "1" is Hashem, He made the next "1"Adam, then Eve made it "2"(or maybe their two children), after the murder but before Seth they were down to only "3", Cain left, so Seth and his wife and Enosh made it a total of "5". Add back the distant Cain and his wife and Enoch and there's "8"(phooey, there's gotta be a better way!), five more generations until Methuselah, that's a "13"...running out of stuff here....Enoch begets Methuselah in Chapter 5, Verse "21"...yeah, enough.... – Gary Feb 20 '18 at 3:10
• @sah no. As I understand it this isn't a question about numbers which are Fibonacci numbers but rather about the set of them. So a fact about the number 8 won't work here, whereas a fact about the number e will work at the other question. – Double AA Feb 26 '18 at 1:40
