Answer: 16  
Step-by-step explanation:
9,10,12,x ,20, 25  so we know the median is 14 which is the middle number.
Since the numbers are 6 it means there will be 2 middle numbers and if you divide them it will be 14.
we know one of the middle numbers is 12 and we trying to find x .
So we could use the equation x  + 12 = 2(14) 
                                                   x + 12 = 28 
                                                      -12   -12  
                                                 x= 16  so X is 16.       check:  16+12=28/2 is 14.
