The Fibonacci Sequence by Nandipha Ndenda What is the fibonnaci sequence? The fibonnaci sequecne is a series of numbers where each number is the sum of the two preceding ones. It starts like this: 0, 1, 1, 2, 3, 5, 8, 12, 21, 34,… Mathematically it can be defined as: F(n) = F(n-1) + F(n-2) An example using the sequence above: F(3) = F(3-1) + F(3-2) F(3) = F(2) + F(1) F(3) = 1 + 0 F(3) = 1 An example of the fibonnaci sequence in everyday life: The number of petals in flowers often follow the Fibonnaci numbers (e.g., lillies have 3 petals followed by another 3 then 6, then 9, etc…) What aspect I find interesting of the fibonnaci sequence: One of the mysterious things is how mathematics can always be applied things about nature. As mentioned above, the numbers of petals on flowers often follow the fibonnaci sequence. What fascinates me about this is why this happens. Scientists believe flowers grow in this sequence to maximise sunlight exposure and efficiently pack seeds in the centre.
