Median is the middle number or the average of the middle numbers when two numbers happen to be in the middle of an ordered numbers.12 and $x$ happens to be in the middle and so the median is the average (the sum of the numbers divided by 2) of 12 and $x$The median is therefore calculated as:Now calculate for the value of $x$Every number is being divided by 1We can therefore write the above equation as:You can cross multiply to solve for the value of $x$$\;1 \times (12+x)=14 \times 2$$\;12+x=28$$\;x=28-12$$\;x=16$
