## Fibonacci

"In mathematics, the Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and characterized by the fact that every number after the first two is the sum of the two preceding ones" - Wikipedia description of the Fibonacci numbers.

That means starting with the numbers 0, 1 and we write down the next numbers in the sequence we will be getting an infinite amount of numbers.

What it has to do with DotO? - the chalkboard you find shows the depiction and the first numbers in the Fibonacci sequence. We get:

0, 1, 1, 2, 3, 5, 8, 13

## Calculation

Using the rules for the Fibonacci numbers we can calculate:

- 0
- 1
- 1 + 1 = 2
- 1 + 2 = 3
- 2 + 3 = 5
- 3 + 5 = 8
- 5 + 8 = 13

The Vault

In the vault we have 6 safes which need - if we count the safe with key locks as a normal safe - 6 x 3 = 18 numbers. Since we only have 8 (counting any number from 10 up as 2 numbers since the pads only feature numbers from 0 - 9) which means we have to add numbers to our list.

Done right following the Fibonacci numbers we would get a list with the numbers 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144

To open all safes we can now just pack the numbers into packets of 3 to fit into the locks:

- 1 - 011
- 2 - 235
- 3 - 813
- 4 - 213 This one can be skipped as it is outfitted with different locks.
- 5 - 455
- 6 - 891
