    Study Notes

    Fibonacci Numbers in Nature

    • Fibonacci numbers appear in nature, such as in the arrangement of leaves, the branching of trees, flower petals, and the pattern of seeds in a sunflower.
    • Common examples include pinecones and the spiral shells of certain snails.

    Next Number in the Sequence

    • The Fibonacci sequence begins: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144.
    • The next number in the sequence after 144 is 233.

    Recursive Formula

    • The Fibonacci sequence can be defined recursively as:
      • F(n) = F(n-1) + F(n-2) for n > 1
      • Starting values: F(0) = 0, F(1) = 1.

    Finding F(16)

    • To determine F(16), use the recursive formula:
      • Calculate previous Fibonacci numbers: F(15) + F(14).
      • Continuing this process results in F(16) = 987.

    Mathematical Language

    • Mathematical ideas are expressed using formal mathematical language, which encompasses symbols, equations, and notations to articulate concepts clearly and precisely.

    Real-life Examples

    • Real-life instances of Fibonacci numbers can be seen in the distribution of branches in trees, the arrangement of pine needles, and patterns in various living organisms.

    Sum of Fibonacci Numbers

    • The sum of F10 (55) and F9 (34) equals 89.

    Value of F(17)

    • Following the recursive sequence, F(17) can be calculated as F(16) + F(15) resulting in F(17) = 1597.
