The mean of (54,825)^2 and (54,827)^2 =
Choose the correct choice from the following answers
A) (54,821)^2	B) (54,821.5)^2	C) (54,820.5)^2	D) (54,826)^2 + 1	E) (54,821)^2 – 1
54825^2 = (54826-1)^2 = 54826^2 + 1^2 - 2*54826*1   54827^2 = (54826+1)^2 = 54826^2 +1^2 + 2*54826*1   Taking the average of above 2 , we get (54826)^2 +1   hence the answer is (54,826)^2 + 1
