How random this numbers look,
21081461046286104621816
Here the system I used to get them, first pick the seed,
13128
then add the value of the 2nd number to the 1st and write it between them and the 3rd to 2nd and write it between them and etc.
143213218
and repeat again 2nd to 1st etc. to get more numbers.
15473523143523198
last step double each number 1>2 5>20 etc.

Is it random or not because I want to use as a one time pad. so is it random even if you know how I generate them?
