One number is missing from this data set

18, 24, 22,30,26,___,25

The median of the data set is 24. What is the greatest possible value of the missing number

Respuesta :

23, it has to be less than 24 since 25, 26, and 30 are greater than 24.
The greatest possible value is 24. It's not more than 24 and 24 will still be in the middle :)
