Middle Arithmetic Mean ( ▁x_0 )
Abstract
In this study, we define the concepts of an arithmetic mean or ordinary arithmetic mean (▁x), maximum arithmetic mean (▁x_(+1) ) , minimum arithmetic mean (▁x_(-1) ) , middle arithmetic mean (▁x_0 ) , the numerical difference between two numbers ND , the relative difference between two numbers RD , we compare between the ordinary arithmetic mean (▁x) and the middle arithmetic mean (▁x_0 ) by the value of the relative difference between them and we show that if x=1 ,2 ,3 ,…,n , then ▁x=▁x_0.
