Question

If the arithmetic mean of x,x+3,x+6,x+9 and x+12 is 10. Find its median

Answer 1

Answer:

x=4

median=10

Step-by-step explanation:

x,x+3,x+6,x+9 and x+12 is 10

x+(x+3)+(x+6)+(x+9)+(x+12)/5= 10

5x+30=50

5x=50-30

5x=20

x=4

x,x+3,x+6,x+9,x+12

4,4+3,4+6,4+9,4+12

4,7,10,13,16

median=10
