Baseline logic sequence
The numbers given are
5 25 29 85 89
.
Hint…
The following number is based only on the previous number, and none of the others.
Hint…
You need to square something.
Hint…
Look at the digits in the previous number.
Solution
Sum the squares of each digit in the previous number.
- F_{n+1} = [ (F_{n})_{(digit 1)} ]^{2} + [ (F_{n})_{(digit 2)} ]^{2} + ... + [ (F_{n})_{(digit i)} ]^{2}
Starting number and digit. | 5 | |
The digit in 5 is only 5. | 5^{2} = 25 | 25 |
The digits in 25 are 2 and 5. | 2^{2} + 5^{2} = 29 | 29 |
The digits in 29 are 2 and 9. | 2^{2} + 9^{2} = 85 | 85 |
The digits in 85 are 8 and 5. | 8^{2} + 5^{2} = 89 | 89 |
The digits in 89 are 8 and 9. | 8^{2} + 9^{2} = 145 | 145 |

The numbers given are
1 3 6 10 15 21 28 36 45
.
Hint…
Look at the differences.
Solution
To the previous number, add the difference between the two previous numbers + 1.
- F_{n+1} = F_{n} + [ ( F_{n} - F_{n-1} ) + 1 ]
Starting number. | 1 | |
Second number. | 3 | |
2 | 3 + 2 + 1 = 6 | 6 |
3 | 6 + 3 + 1 = 10 | 10 |
4 | 10 + 4 + 1 = 15 | 15 |
5 | 15 + 5 + 1 = 21 | 21 |
6 | 21 + 6 + 1 = 28 | 28 |
7 | 28 + 7 + 1 = 36 | 36 |
8 | 36 + 8 + 1 = 45 | 45 |
9 | 45 + 9 + 1 = 55 | 55 |
New logic sequence enabled #2
The numbers given are
1011011001 1000000000 101010111
.
Hint…
The numbers are easier to comprehend if they are converted into decimal (or base 10 numbers).
Hint…
The numbers are written in binary (or base 2 numbers). For an explanation see Wikipedia's article on the binary system. Or you can use one of the many converters that exists on the internet, for example this one.
Hint…
The numbers converted into decimal (or base 10) are
729 512 343
.
Hint…
Think cubic.
Partial solution
The numbers given are the cube of the numbers 9, 8 and 7, respectively. The next number will be the cube of 6.
729 = 9^{3} |
512 = 8^{3} |
343 = 7^{3} |
216 = 6^{3} |
Hint…
However, you need to answer in the same way as you were given the numbers.
Hint…
You need to convert 216 into binary (or base 2).
Solution
The number you need to type in is
11011000
.Final logic sequence required for initialisation
The numbers given are
312213 212223 114213 31121314 41122314 31221324
.
Hint…
The following number is based only on the previous number, and none of the others.
Hint…
You need to count something.
Hint…
Say the digits in the number one by one.
Hint…
Then compare this to the previous number.
Solution
The next number is based on counting the occurrences of each individual digit in the previous number.
312213 | This number has 2 1-digits, 2 2-digits, 2 3-digits. |
212223 | This number has 1 1-digit, 4 2-digits, 1 3-digit. |
114213 | This number has 3 1-digits, 1 2-digit, 1 3-digit, 1 4-digit. |
31121314 | This number has 4 1-digits, 1 2-digit, 2 3-digits, 1 4-digit. |
41122314 | This number has 3 1-digits, 2 2-digits, 1 3-digit, 2 4-digits. |
31221324 | This number has 2 1-digits, 3 2-digits, 2 3-digits, 1 4-digit, which gives the final number and answer. |

Tier 2
- Go to the security terminal.
- Hack the terminal and find out about the mole.
Abstracted data prepared
The numbers given are
42 66 70 78 102 105
.
Hint…
Look at the factors in the numbers.
Hint…
Look at the prime factors in the numbers.
Solution
The numbers are sphenic numbers. Each number is composed of factors of three different prime numbers, each used only once. Based on all possible combinations of three different primes the end results have been sorted to create a fixed ordered sequence. The next number is
110
.Processing new sequence, left to right
The numbers given are
2 3 3 5 10 13 39 43 172 177
.
Hint…
The following number is based on the previous number, and then something else.
Hint…
You cycle on using addition and multiplication.
Hint…
Another way is to look at the differences.
Hint…
Start with the difference between 3 and 2, or in other words 1.
Solution
As mentioned, each number is based on the previous number which is either added with, or multiplied with, an increasingly higher number.
Starting number. | 2 | |
+ 1 | 2 + 1 = 3 | 3 |
* 1 | 3 * 1 = 3 | 3 |
+ 2 | 3 + 2 = 5 | 5 |
* 2 | 5 * 2 = 10 | 10 |
+ 3 | 10 + 3 = 13 | 13 |
* 3 | 13 * 3 = 39 | 39 |
+ 4 | 39 + 4 = 43 | 43 |
* 4 | 43 * 4 = 172 | 172 |
+ 5 | 172 + 5 = 177 | 177 |
* 5 | 177 * 5 = 885 | 885 |
Abstracting new data. Emirps found.
The numbers given are
13 17 31 37 71 73 79 97 107
.
Hint…
Each of these numbers are prime numbers.
Hint…
Emirp becomes something else if you turn it around.
Hint…
You might want to look up the definition of emirp.
Solution
The hint given by the game really tells it all. An emirp is a prime number that when reversed also becomes a prime, but excluding palindromic primes. The next number is
113
.Generating final sequence...
The numbers given are
377 610 987 1597
.
Hint…
Italian.
Hint…
Although Indians discovered/published it much much earlier.
Hint…
(Italian) rabbits.
Hint…
Within number theory and mathematics it is a very well known number sequence.
Hint…
You can also look at the differences.
Solution
The numbers are Fibonacci numbers. Each number is the sum of the two previous numbers. The next number is
2584
