What is the Fibonacci Sequence & the Golden Ratio? Simple Explanation and Examples in Everyday Life

The Fibonacci sequence is a series of numbers in which a given number is the addition of the two numbers before it. So, if you start with 0, the next number will be 1, followed by 1, followed by 2, followed by 3 and so on. As you can see, every number in this series or sequence is obtained by adding the two preceding numbers. This simple series of numbers is referred to as the Fibonacci sequence for Fibonacci series. And individual numbers in this sequence are often called Fibonacci numbers. To the uninitiated, it may just seem like a series of numbers, but the Fibonacci sequence has been discovered and rediscovered in various forms, not only in mathematics, but also in nature and our everyday lives. There’s another exciting offshoot of the Fibonacci sequence - the golden ratio. Seashells are one of the most common examples of the golden spiral in nature. Ocean waves, hurricanes, flower buds, snail shells, spider webs are some of the many naturally-occurring examples.
