# What will replace question mark and why?

9 is the answer bcoz…

1+2=3

2+4=6

So 3+6=9

1 2 3 table of 1

2 4 6 table of 2

3 6 9 table of 3

If we take horizontally or vertically both are same

9,it mantain the series in 1st colum it comes alternet,2nd colum it mentain diffrence 2 ,3rd column it mentain diffrence 3
