Information about Fibonacci numbers

Faibonacci discovered when observing rabits that they multiplied 1,2,3,5, he noticed that there was a pattern to the numbering if you add the two proceeding numbers you will come up with the next number that you need. Example 1 + 2 = 3, 2 + 3 = 5, the next in line would be 3 + 5 = 8 and so on.

In the same mannor you can figure out this problem.

10, _____, 24, _____, _______, 100, _____, ______, 686

10 + _____ = 24, which is 14

14 +24 = 38

24 + 38 = 62

38 + 62 = 100

62 + 100 = 162

100 + 162 = 262

162 + 262 = 424

262 + 424 = 686

There isn't much to it. If the first number is blank and you need to figure it out you can always use the X, 2X, 3X, etc thing.

If you know the first number and don't the other numbers, suppose the first number is 4 you use:

4, x + 4, X + 4 + 4 or X + 8, X +4 + X + X + 4 or 3X + 8, etc. until you get to a number.
