    There is NO "necessary" 'next number' in any sequence. Sometimes you can try to "guess" a simple pattern or formula, such as "add the same thing each step" (arithmetic sequence) or "multiply by the same thing each step". I note that the third number here is the negative of the sum of the first two but I don't see any clear way to get the fourth number.

    I don't think It's possible. Are you 100% sure you can make the next number?
    I've just created an A4 piece of paper full with random numbers that don't match.
    Nothing Matches.
