Fibonacci Sequence Tutorial

Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1. This sequence has been fascinating mathematicians and programmers for centuries. In this tutorial, we will explore the Fibonacci sequence and its applications.

What is the Fibonacci Sequence?

The Fibonacci sequence starts with 0 and 1, and the next numbers are found by adding the two numbers before it. For example:

• 0, 1, 1, 2, 3, 5, 8, 13, 21, ...

Here is a list of the first few Fibonacci numbers:

• 0
• 1
• 1
• 2
• 3
• 5
• 8
• 13
• 21
• 34

As you can see, each number in the sequence is the sum of the two previous numbers.

Generating Fibonacci Sequence

You can generate the Fibonacci sequence using various programming languages. Here is an example in Python:

def fibonacci(n):
    if n <= 0:
        return []
    elif n == 1:
        return [0]
    elif n == 2:
        return [0, 1]
    else:
        sequence = [0, 1]
        for i in range(2, n):
            sequence.append(sequence[i - 1] + sequence[i - 2])
        return sequence

print(fibonacci(10))

This code will return the first 10 numbers of the Fibonacci sequence.

Applications of Fibonacci Sequence

The Fibonacci sequence has numerous applications in mathematics, nature, and computer science. Here are a few examples:

• Nature: Many plants and animals exhibit Fibonacci patterns. For example, pinecones, pineapples, and sunflowers have Fibonacci spirals.
• Computer Science: The Fibonacci sequence is used in algorithms, data structures, and computer graphics.
