Question 1189041
<br>
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.<br>
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.<br>
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".<br>
