1.

Find the mean of x , x + 2 , x + 4 , x + 6 , x + 8.

Answer»

Given numbers are x , x + 2 , x + 4 , x + 6 , x + 8.

Sum of numbers = x+(x+2) + (x+4) + (x+6) + (x+8)

= 5x + 20

Total Numbers = 5

Now, Mean = (Sum of numbers) / (Total Numbers)

= \(\frac{(5x+20)}{5}\)

= \(\frac{5(x + 4)}{5}\)

= x + 4

Mean = x + 4
