It could be 2 because the rest are odd number It could be 9 because the rest are prime numbers
13 & 7/9
The mean is found by adding the values together and dividing by the number of values. 5+7+9+11+13+9 = 54 54 divided by 6 is 9. The mean of 5, 7, 9, 11, 13, 9 is 9.

It could be 2 because the rest are odd number It could be 9 because the rest are prime numbers
It probably is 18 because if divided by 2 they are 3, 5, 7, 9, 11 and 13 but 9 is not a prime number
18-the correct number should be 20.
13 & 7/9
The smallest number divisible by 5 7 9 11 13 and 15 is 45,045.
9 - all the rest are prime
The mean is found by adding the values together and dividing by the number of values. 5+7+9+11+13+9 = 54 54 divided by 6 is 9. The mean of 5, 7, 9, 11, 13, 9 is 9.
Arrange the numbers in ascending order: 7 9 9 12 13 15 16 and the middle number is the median which is 12

The answer is 12 every other numbers are odd numbers, but 12 is an even number
