Question 1156683
<br>
There is no mathematics involved in trying to solve ANY problem like this.<br>
You can put any numbers in the blanks and it will be a valid sequence.<br>
The only way to know the "right" answer is to ask the author of the problem what the answer is.<br>
If you are so inclined, spend as much (or as little) time as you want trying to find a pattern which allows you to complete the sequence -- but know that any answer you come up with might be "wrong".<br>
