If the average of the numbers 4,6,x and 2x is 10 what is the value of x?
Answers: 2
, which is the same as 
. You can apply this equation to your problem to start solving this problemmusing the serie of numbers you have: (4,6,x,2x).Following the previous equation, in this particular case n=4 (there are four values to calculate the average value), then the average can be calculated as follow: 
and this equals 
⇒
. Substracting 10 from both sides, and dividing this result by 3, we get x=10.
