  2. 21 (number) - Wikipedia

    en.wikipedia.org/wiki/21_(number)

    In decimal, the number of two-digit prime numbers is twenty-one (a base in which 21 is the fourteenth Harshad number). [8] [9] It is the smallest non-trivial example in base ten of a Fibonacci number (where 21 is the 8th member, as the sum of the preceding terms in the sequence 8 and 13) whose digits (2, 1) are Fibonacci numbers and whose digit ...

    The number in the n-th month is the n-th Fibonacci number. [21] The name "Fibonacci sequence" was first used by the 19th-century number theorist Édouard Lucas. [22] Solution to Fibonacci rabbit problem: In a growing idealized population, the number of rabbit pairs form the Fibonacci sequence.

    The list on the right shows the numbers 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377 (the Fibonacci sequence). The 2, 8, and 9 resemble Arabic numerals more than Eastern Arabic numerals or Indian numerals. The Liber Abaci or Liber Abbaci [1] (Latin for "The Book of Calculation") was a 1202 Latin work on arithmetic by Leonardo of Pisa ...

  5. Fibonacci - Wikipedia

    en.wikipedia.org/wiki/Fibonacci

    In the Fibonacci sequence, each number is the sum of the previous two numbers. Fibonacci omitted the "0" and first "1" included today and began the sequence with 1, 2, 3, ... . He carried the calculation up to the thirteenth place, the value 233, though another manuscript carries it to the next place, the value 377.

    Each rectangle has a Fibonacci number F j as width (blue number in the center) and F j−1 as height. The vertical bands have width 10. The vertical bands have width 10. In mathematics , Zeckendorf's theorem , named after Belgian amateur mathematician Edouard Zeckendorf , is a theorem about the representation of integers as sums of Fibonacci ...

  7. Generalizations of Fibonacci numbers - Wikipedia

    en.wikipedia.org/wiki/Generalizations_of...

    The usual Fibonacci numbers are a Fibonacci sequence of order 2. The cases n = 3 {\displaystyle n=3} and n = 4 {\displaystyle n=4} have been thoroughly investigated. The number of compositions of nonnegative integers into parts that are at most n {\displaystyle n} is a Fibonacci sequence of order n {\displaystyle n} .

  8. Fibbinary number - Wikipedia

    en.wikipedia.org/wiki/Fibbinary_number

    For instance, the Zeckendorf representation of 19 is 101001 (where the 1's mark the positions of the Fibonacci numbers used in the expansion 19 = 13 + 5 + 1), the binary sequence 101001, interpreted as a binary number, represents 41 = 32 + 8 + 1, and the 19th fibbinary number is 41.
