Let two =2
Let one = 1
Let the average (mean) of one and two = Ave
Then one + two = 2Ave
Rearranging;
two = 2Ave - one
and two – 2Ave = -one
multiplying both side by two or its equal
two(two – 2Ave) = -one(-one + 2Ave)
two2 – 2xtwox2Ave = one2 – 2 x one x Ave
Add Ave2 to both sides
two2 – 2x one x Ave + Ave2 = one2 -2 x one x Ave + Ave2
(two - Ave)2 = (one - Ave)2
Take the square root of both sides
two - Ave = one - Ave
Add Ave to both sides
two = one
