This question already has an answer here:
I have a sequence of numbers like 1,7,22,45,12,96,21,45,65,36,85,14,51,16,18,17,16....65...
IS there any formula to check whether the sequence is random or not ?
In my case
- odd numbers are not random since previous+2
- even numbers are not random
- the numbers can be repeated in a sequence but must be far away,
- we cannot generate the sequence using any formula like (x+2)^2 -2x like...
