According to question,
(x+8 + x+6 + x + 4 +x + 2 + x) / 5 = 24
=> 5x + 20 = 120
=> 5x = 100
=> x = 20
(x+8 + x+6 + x + 4 +x + 2 + x) / 5 = 24
=> 5x + 20 = 120
=> 5x = 100
=> x = 20

Mean = (Sum of observations)/(Number of observations)
24 = (x + x + 2 + x + 4 + x + 6 + x + 8)/5
24 = (5x + 20) / 5
24 = 5(x + 4)/5
24= (x + 4)
x =24 -4
x= 20
24 = (x + x + 2 + x + 4 + x + 6 + x + 8)/5
24 = (5x + 20) / 5
24 = 5(x + 4)/5
24= (x + 4)
x =24 -4
x= 20
