Fibonacci Numbers

Today I learned about Fibonacci Numbers. It was very confusing especially when you're writing Fibonacci Numbers up to the twentieth number.


When you do Fibonacci Numbers you add the two previous numbers together to get the next number. The first 15 numbers are... 

1. 1
2. 1
3. 2
4. 3
5. 5
6. 8
7. 13
8. 21
9. 34
10. 55
11. 89
12. 144
13. 233
14. 377
15. 610
