What is The Fibonacci sequence?
The Fibonacci sequence is a series of numbers where each is the sum of the two before it: 0, 1, 1, 2, 3, 5, 8, 13… It appears surprisingly often in nature, and its ratios approach the golden ratio.
See it, don’t just read it.

Key things to understand
- 1Each number is the sum of the previous two (2+3=5, 3+5=8…).
- 2It starts 0, 1, 1, 2, 3, 5, 8, 13, 21…
- 3The ratio of consecutive terms approaches the golden ratio (~1.618).
- 4It appears in flower petals, pinecones, and spiral shells.
Frequently asked questions
- How does the Fibonacci sequence work?
- Start with 0 and 1, then each new number is the sum of the two before it.
- Where is the Fibonacci sequence found in nature?
- In the arrangement of leaves, flower petals, pinecones, and spiral shells.
- How is it related to the golden ratio?
- As the sequence grows, the ratio of consecutive numbers gets closer and closer to the golden ratio.
