Question

If the mean of x,x+2,x+4,x+6,x+8 is 24 Find the value of x.​

Answer 1

$Mean \\ \\ \frac{x + x + 2 + x + 4 + x + 6 + x + 8}{5} = 24$

$Mean \\ \\ \frac{5x + 10}{5} = 24 \\ \\ 5x + 10 = 120 \\ \\ 5x = 120 - 10 \\ \\ 5x = 110 \\ \\ x = \frac{110}{5} \\ \\ x = 22$

Answer 2

x = 20.

Step-by-step explanation:

• mean of x,x+2,x+4,x+6,x+8 is 24.

To Find:

• Value of x.

Formula used:

• Mean = Sum of observations/Total no. of observations

According to question, we have

24 = (x+x+2+x+4+x+6+x+8)/5

120 = 5x+20

5x = 120-20

5x = 100

x = 100/5

x = 20

So, the value of x will be 20.
