The Fibonacci Sequence
Date : 11/12/2023
Fibonacci numbers can be illustrated as a spiral with squares representing the widths of the numbers in the sequence. The squares fit nicely together, forming the spiral. In this example, 1 plus 1 equals 2, 1 plus 2 equals 3, 2 plus 3 equals 5, 3 plus 5 equals 8, 5 plus 8 equals 13, etc.
Descri ption automatically generated">Fibonacci numbers appear in many contexts in our lives and surroundings, for example, the number of the petals in a flower, the seed heads of a flower, paintings and a lot more. In fact, the beauty of a human face is based on Golden Ratio, a constant which can be calculated from the numbers in the Fibonacci sequence.
The Golden Ratio is a constant and is represented by the symbol phi, 𝜙. If we have 2 numbers, A and B, with B > A,they are said to be in golden ratio, if, 𝜙(A+B) / B = 𝐵 / 𝐴 ≡𝜙 Phi has the value 1.618 and we can see this value emerge from the Fibonacci sequence by dividing successive numbers in the sequence:3/2 =1.5, 5/3 = 1.67, 8/5 = 1.6, 13/8 = 1.625, 21/13 = 1.615, 34/21 = 1.619, 55/34 = 1.618
