in Algorithms

If given a set of numbers (14 digits each) with the same algorithm, is it possible to find the algorithm and generate more numbers?

Sorry my english is terrible... would you please be so kind as to write more detailed information about what do you need? :-)

Any questions? Just ask!

Yepp, or almost.

Grab a math book and learn or relearn how to get a function from a set of data.

(if you want to be advanced you could do a neural network that learn's from youre data...)

:

You could look for differences between the values,

Do they all end with 0 or/and 5 ( divisible by 5 or 10 )?

You have to try and look for patterns in the numbers, they may all be PRIME numbers?

They may all have a common denominator like 5 or 10 or a bigger or a smaller number.

They may be numbers of a series like FIBONACCI where the next number is the sum of the previous two. 1,2,3,5,8,13....and so on.

There are lots of tests for numbers.

Another is if you add all the digits like

927631836459045 is divisible by 9 as if all the digits added are divisible by 8 then the bigger number is.

Just look at

18

27

36

45

54

63

72

90

99

108 etc and you get the idea 1+8=9 so 108 is divisible by 9.

Lots of things like the above can be tested.
