What's the common number in the followng table: x 0, 3, 6, 9, 12 and Y 2, 4, 6, 8, 10?

Question

What's the missing number to make this table work?

Answer 1

Hi Sherry,

The question wants you to find which number the two tables have in common. Each table has a 6, so 6 is a common number to the two tables. The tables share no other numbers in common so 6 is the only number in common.
