Question

defference of squares of two consecutive even numbers is 99 what will be smaller even number

Answer 1

Let the two consecutive even numbers be x and (x-2).

Given

x^2 – (x-2)^2 = 99 = x^2- (x^2 – 4x + 4) = 99 =x^2 – x^2 + 4x -4 = 99 = 4x = 99.

Here we can say that since we do not get a value which has no decimal points.

There exactly ain’t any even number which satisfies the given condition in your question.
