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:

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
x= 5.25
