Suppose the first fibonnaci number is 0 and the second is 1. What is the sixth fibonnaci number? ans. 5 6 7 8

The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones, usually starting with 0 and 1.

Here's how you can calculate the sixth Fibonacci number:

1. Start with the first two Fibonacci numbers: 0 and 1.
2. The third Fibonacci number is the sum of the first two numbers: 0 + 1 = 1.
3. The fourth Fibonacci number is the sum of the second and third numbers: 1 + 1 = 2.
4. The fifth Fibonacci number is the sum of the third and fourth numbers: 1 + 2 = 3.
5. The sixth Fibonacci number is the sum of the fourth and fifth numbers: 2 + 3 = 5.

So, the sixth Fibonacci number is 5.
