The mean of (54,824)^2 and (54,826)^2 =  Options
A) (54,821)^2
B) (54,821.5)^2
C) (54,820.5)^2
D) (54,825)^2 + 1
E) (54,821)^2 – 1
54824^2 = (54825-1)^2 = 54825^2 + 1^2 - 2*54825*1   54826^2 = (54825+1)^2 = 54825^2 +1^2 + 2*54825*1   Taking the average of above 2 , we get (54825)^2 +1   hence the answer is (54,825)^2 + 1
