Answer 1

Answer:

9

Step-by-step explanation:

median: The middle number after the numbers have been sorted into ascending or descending order.

Mean: The quotient of the numbers added together then divided by the amount of numbers.

So if 9 were the missing number the median would be 5 because in ascending order it would look like this:

1, 3, 5, 7, 9

and as you can see 5 is in the middle.

The mean would also be 5 because

1+ 3+ 5 + 7 +9 =25

and 25 divided by 5 equals 5

So therefore the missing number must be 9.

(Also it was obvious that they just added 2 to each number)
