Question

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

Answer 1

Answer:

X=20

Step-by-step explanation:

If the mean is 24

Then,

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

Therefore, on calculating it is

$\frac{5x + 20}{5} = 24$

Then,

5x+20=24×5

5x+20=120

5x=120-20

5x=100

Hence X=100/5

Which is X=20

Answer 2

Step-by-step explanation:

I'd the mean is 24 then that given

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

5x+20/5=24

5x+20=24×5

5x=120-20=100

X=100/5=20
