What is Fibonacci Sequence ?
1
How does the Fibonacci Sequence Work ?
The Fibonacci sequence is derived from the Fibonacci numbers. The Fibonacci numbers
are as follows:
0,1,1,2,3,5,8,13,21,34,55,89,144….and so on.
These numbers are obtained by adding the two previous numbers in the sequence to obtain
the next higher number.
Example: 1+1=2, 2+3=5, 5+8=13…
The formula : Fn = Fn-1 + Fn-2
Every third number is even and the difference between each number is .618 with the
reciprocal of 1.618 . These numbers are known as the “golden ratio” or “golden mean” .

What is the History of the Fibonacci Sequence ?
4
Fibonacci Sequence in Petal Patterns.
The Fibonacci Sequence can be
seen in most petal patterns.
For instance most daisies have
34, 55, or 89 petals. (The 9th, 19th,
and 11th Fibonacci Numbers).
5
Fibonacci Sequence in Sunflowers.
The Fibonacci Sequence can be found in
a sunflower heads seed arrangement.
The arrangements of seeds is based
upon the golden mean which corresponds
to the “golden angle” of 137.5 degrees.
The seeds are arranged in consistent
pattern of 137.5 degrees.
This gives the flower the optimal filling
ratio fir its seeds.
6
Fibonacci Sequence in Seashells.
The Fibonacci numbers directly correspond
to the spiral found in seashells.
The numbers from what are called Fibonacci
rectangles or “golden rectangles”.
The rectangles are unique because each
rectangle has sides equal to the length of the
Fibonacci numbers.
Within these rectangles we can create a
spiral with cross sections equal to exactly
1.618 (the “golden mean” with the
corresponding angle of 137.5 degrees).
