What number goes on top?

The blank would be

The blank would be 33. If you follow the pattern, you will see you first add 3 and 4 which is 7. Then 5 and 3 which is 8. The 9 comes from 7, 8, ... the dots would be 9. 7+9=16 and 9+8= 17. So you will need to add 16 and 17 which is 33.

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
