(7+5+13+x+9)÷5=10
(34+x)÷5=10
34+ x = 50
x= 50 - 34
x = 16
(34+x)÷5=10
34+ x = 50
x= 50 - 34
x = 16

Arithmetic mean =
sun of observation / total no. of observation
10 = ( 7 + 5 + 13 + x + 9 )/5
50 = 34 + x
50 - 34 = x
16 = x
sun of observation / total no. of observation
10 = ( 7 + 5 + 13 + x + 9 )/5
50 = 34 + x
50 - 34 = x
