The Fibonacci sequence is a series of numbers in which each number is the sum of the two that precede it.
Starting at 0 and 1, the first 10 numbers of the sequence look like this:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34……
The Fibonacci sequence can be described using a mathematical equation: Xn+2= Xn+1 + Xn
Golden ratio & piral
Two lengths are in the golden ratio when the whole is to the larger as the larger is to the smaller, a proportion that feels calm and balanced.
φ = (1+√5)/2 ≈ 1.618;
φ² = φ + 1, 1/φ = φ − 1.
The Fibonacci spiral is a near‑logarithmic curve that grows by φ each quarter‑turn, A friendly guide for layout and spacing.
From hurricanes to spiral galaxies, nature repeats this gentle growth pattern at every scale.
