Arithmetic mean the average of a set of numerical values, as calculated by adding them together and dividing by the number of terms in the set.
lets take 10 random numbers and calculate Arithmetic mean
25,45,35,77,55,34,87,56,54,67
A.M=25+45+35+77+55+34+87+56+54+67/10
A.M=535/10
A.M=53.5
this way we can calculate Arithmetic mean you should practice this
