Hlw mate!!

25=mean of (5th+6th value)

25=1/2*(2x-8+2x+10)

25=1/2*4x+2

4x+2=50

4x=48

x=12


Hope it helpful

Here is your answer

As it has Total 8 terms

Hence Median is Sum of 4th and fifth term/2

Fourth term = 2x + 10

Fifth term = 2x - 8

Median =
25 = \frac{2x + 10 + 2x - 8}{2} \\25 = \frac{4x + 2}{2} \\ 4x + 2 = 25 \times 2 \\ 4x = 50 - 2 \\ 4x = 48 \\ x = \frac{48}{4} \\ x = 12
Therefore x = 12

Hope it helps you
