6
2
9
3
Answer is Right!
Answer is Wrong!
The answer is 3.
The missing number is the number that, when added to
the other two numbers, gives a multiple of 9.In this case, 2 and 6 are both multiples of 3, so the missing number must also be a multiple of 3. The only answer
choice that is a multiple of 3 is 3.Therefore, the missing number is 3.
