Question 1101780
<br>
It appears another tutor submitted an empty response to your question....<br>
And in fact an empty response is as good as any other, because there is no way to know the "right" answer to this problem, or any other similar problem.<br>
Without any instructions as to WHAT KIND of pattern is shown, we could put any number we want in for Y, and it would be a valid answer.<br>
If this is the complete problem as it was given to you, then there is on point in your spending any time on it, because any answer you might come up with might not be "right".<br>
If there were some instructions accompanying the problem as you show it, re-submit the problem, showing the WHOLE problem.  It MIGHT then be possible to determine the answer to the problem.
