In all three of these examples, as in EVERY OTHER SIMILAR EXAMPLE, the is NO WAY to know the "right" answers. In all such problems, ANY next number forms a valid sequence.
For a problem like this to be valid, a description of what type of sequence it is must be provided in order to have a chance of determining the correct next number.
Spend as much -- or as little -- time as you want trying to find a logical pattern in the numbers that are shown to predict the next number in each sequence, knowing that any answer you come up with might not be "right".
