find random numbers that are = to the first 2 number of a list.

read again my previous post. If you don't care about the sequences that don't satisfy the condition, as you just throw them away, you don't need to generate sequences, till you get one that satisfied the condition.

I do care about the condition and the next numbers cause they are link.

Say you have 13 millions possibilities of series of numbers looking 6 numbers on 49 . You want to extract the series where the first 2 numbers are 1 and 2 and list it. Problem it takes too long. List all series will take forever so we must narrow the search. How to do it with 12 ram pc?

What i am interested in, is to analyze what subsequent numbers the computer will generate after 1 and 2. But they have to be part of the original serie and not be added afterward.

Why? You have not explained why.

I am wondering if its possible to use past numbers to predict the next numbers. Is it possible that the Pseudorandom number generator of our computers behave the same as any supercomputer. Of course, computers dont use the same algorithm to generate random numbers.
