Find the geometric mean between 6x and 24x.
A.)4
B.)12
C.)12x

Do you really expect someone to do all of these homework assignments for you?

Please stop just dumping these homework questions.
At least tell us what your choices are, and we will tell you if you are correct 
I think it 12

Am i wrong?

yes

12x?

that's better. The sequence is thus
6x 12x 24x 48x . . .
the geometric mean between a and b is √ ab
Fo this problem, that's √[(6x)(24x)] = √ 144x^2 = 12x 
12x
