What is the rule for the Fibonacci sequence?

Answer 1

The rule of the Fibonacci sequence is simple. Take the previous number in the sequence, and add it to the current number.

The sequence starts with 0 and 1.

0, 1

So, add 0+1=1. The sequence now contains three numbers.

0, 1, 1

Now, add 1+1=2. This brings us to four numbers.

0, 1, 1, 2

Add 1 and 2. (1+2=3)

0, 1, 1, 2, 3

Now it gets a bit tricky. Add 2+3=5, so the next number is 5.

0, 1, 1, 2, 3, 5

Continue to add the numbers accordingly. (3+5=8)

0, 1, 1, 2, 3, 5, 8

Proceed.

0, 1, 1, 2, 3, 5, 8, 13, 25, 38, 63, 101, 164...
