The value of x is 13.

Step-by-step explanation:

Given : If the numbers 3,6,7,10,x,15,19,20,25,31 are in ascending order and their median is 14.

To find : Calculate the value of x ?

Solution :

The numbers 3,6,7,10,x,15,19,20,25,31 are in ascending order.

The median of even number is

$M=\frac{\frac{nth}{2}+(\frac{nth}{2}+1)}{2}$

Here, n=10

$M=\frac{\frac{10th}{2}+(\frac{10th}{2}+1)}{2}$ term

$M=\frac{5th+6th}{2}$ term

$14=\frac{x+15}{2}$

$x+15=28$

$x=13$

Therefore, the value of x is 13.
