About the Fibonacci Sequence

The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones. It appears in many areas of mathematics and science, from the arrangement of leaves on a stem to the spiral patterns of shells.

Mathematical Properties
  • Each number is the sum of the two preceding ones: F(n) = F(n-1) + F(n-2)
  • The ratio of consecutive Fibonacci numbers approaches the Golden Ratio (approximately 1.618033988749895)
  • Fibonacci numbers are related to the golden spiral, which appears frequently in nature
  • The sequence grows exponentially
Applications
  • Computer algorithms and data structures
  • Financial market analysis
  • Architecture and design
  • Music composition
  • Natural patterns in plants, flowers, and shells
Fun Facts
  • Leonardo of Pisa (also known as Fibonacci) introduced these numbers to Western mathematics in 1202
  • The original problem was about rabbit population growth
  • Any 4 consecutive Fibonacci numbers can be used to generate a Pythagorean triple
  • The sum of any 10 consecutive Fibonacci numbers is divisible by 11
