Question

If the mean of x, x + 2, X +4, X + 6 and x + 8 is 13, find the value of x.​

Answer 1

Answer : x = 45

Step-by-step explanation:

• Mean = $\frac{ Sum Of Observation }{Total Number Of Observation}$  = $\frac{x+x+2+x+4+x+6+x+8}{5}$ = $\frac{x+20}{5}$
• 13 = $\frac{x+20}{5}$
• x = 65-20
• x = 45
