If the mean of x, x+2,x+4,x+6,x+8 is24 , find x

1.	If the mean of x, x+2,x+4,x+6,x+8 is24 , find x
Answer» AnsWer : X = 20. GiveN : Mean = 24. OBSERVATION x , x + 2 , x + 4 , x + 6 , x+ 8. To FinD : The VALUE of x. SolutioN : We have, Formula. $\tt Mean = \dfrac{Sum \: of \: Observation}{ No. \: of \: Observation}$ ★ Here, NUMBER of Observation is 5. $\tt : \implies Mean = \dfrac{x + x + 2 + x + 4 + x + 6 + x + 8}{5}$ $\tt : \implies 24 = \dfrac{x + x + 2 + x + 4 + x + 6 + x + 8}{5}$ $\tt : \implies 24 = \dfrac{5x +20}{5}$ $\tt : \implies 24 = \dfrac{5(x +4)}{5}$ $\tt : \implies 24 = x + 4$ $\tt : \implies x = 20.$ Therefore,the value of x is 20.
