Question

If the following numbers are given in ascending order and their median is 17. Find the value of x.

2 , 3, 9 , x, x+2 , 21 , 25 , 27​

Answer 1

Answer:

16

Step-by-step explanation:

since the given set of values is an even number the median will result 2 middle most numbers.

we have to take mean of those 2 middle most values and we know median is 17.

=》

$\frac{x + x + 2}{2} = 17 \\ \frac{2x + 2}{2} = 17 \\ \frac{2(x + 1)}{2} = 17 \\ x + 1 = 17 \\ x = 17 - 1 = 16$
