Fibonacci Sequence and Golden Ratio

The video introduces the Fibonacci sequence, explaining its formation and significance. It covers the recursive formula and historical context, including its introduction by Fibonacci. The sequence's application is illustrated through the rabbit problem, showing how it models population growth. The video highlights the presence of Fibonacci numbers in nature, such as in flower petals and spirals. It also explores the connection between the Fibonacci sequence, the golden ratio, and the golden spiral, demonstrating their occurrence in natural patterns.

What is the recursive formula for generating the Fibonacci sequence?

• a_n = a_(n-1) * a_(n-2)

• a_n = a_(n-1) - a_(n-2)

• a_n = a_(n-1) + a_(n-2)

• a_n = a_(n-1) / a_(n-2)
