Answer:

Total number = 5

Mean = Sum of total number/ Total number

⇒ (x + x + 2 + x + 4 + x + 6 + x + 6 + x + 8)/5 = 13

⇒ 5x + 20 = 65

5x = 65 – 20 = 45

x = 45/5 = 9

Step-by-step explanation:

good morning

the given observations are x+2x+4,6,x+8

mean = ( x+2x+4+6+x+8) / 3 = (4x+18)/3 =13

4x+18 = 39

4x=39-18

4x= 21

x=21/4
