I need help figuring out these patterens:

1,2,3, ______, _____, ______, _______

2, ______ , 8 , ______, ________, _______

3 , _____, ______, 13, ______, ______, _______

2, _____, _____, ____, ______, 26

2, ____, _____, ______, ______, 11
 
Have you tried any of these? Certainly you can find a pattern with the first one.
 
This is not what you want. It certainly is not what you deserve!
But the brutal fact is that there is no unique answer!
Only the person who wrote the question knows the particular answer.
Therefore, any answer we can give is simply a guess!
In other words, there is no definitive answer. Sorry.
 
Could be. But pka is right: without a formula telling you exactly what process is forming these terms, there is no way to know what the "right" answer is, and there may be quite a few valid answers.

For instance, the second one might be "powers of 2", so you get 2, 4, 8, 16,....

Or it might be "add three at each stage", so you get 2, 5, 8, 11,....

Or it might be recursive, using "2, 6, and then add the two previous terms", so you get 2, 6, 8, 14,....

And on and on. There is just not way to tell.

The point is, these types of problems should be dropped!
If there is no definitive answer then how can it be a mathematical problem?
It is just an exercise in guessing!

That, or educators need to be honest about them.
