For each sequence, choose any number you want and make it the next number. Any next number you choose will make a valid sequence; and any next number you choose will be as good an answer as any purported "right" answer.

Without any information about what kinds of sequences these are, finding "the" answers is merely a guessing game; there is no mathematical reasoning involved.

Whenever you see a problem like this, spend only a very short time (if any!) looking for a pattern in the given numbers ---realizing even then that any pattern you see might not be the "right" one.
