Let's name the first number x and the next number x + 1. So,
x^2 - (x + 1)^2
= x^2 - (x^2 + 2x + 1)
= x^2 - x^2 - 2x - 1
= - 2x - 1
= -(2x + 1)
Thus we can say that, the difference between the squares of two consecutive numbers is equal to the opposite of their sum (means it is their sum, but as a negative number).
Let's do some examples:
2, 3; 2 + 3 = 5
2^2 - 3^2 = 4 - 9 = -5 ( 5 and -5 are opposite numbers, and 5 is the sum of 2 and 3)
13, 14; 13 + 14 = 27
13^2 - 14^2 = 169 - 196 = -27 (27 and -27 are opposite numbers, and 27 is the sum of 13 and 14)

Is The difference between consecutive perfect square numbers is always odd?
Yes, the difference between consecutive perfect square numbers is always odd. If ( n ) is a positive integer, the perfect squares are ( n^2 ) and ( (n+1)^2 ). The difference between them is ( (n+1)^2 - n^2 = 2n + 1 ), which is always odd since ( 2n ) is even and adding 1 results in an odd number. Thus, the difference between any two consecutive perfect squares is consistently odd.
What are 2 consecutive numbers whose squares differ by 17?
The difference between the squares of two consecutive integers j and j+1 is |2j+1|. There are therefore two such pairs where this quantity is 17:-9 and -88 and 9
What are three consecutive square numbers?
There are no three consecutive numbers that are squares. Otherwise, there are an infinite sets of squares of three consecutive numbers: for example, {1,4,9}, or {4,9,16} or {576, 625, 676}

16,25,36 add to 77. They are the squares of consecutive numbers 4,5,6
What two consecutive numbers whose squares differ by 25?
Let the two consecutive numbers be ( n ) and ( n + 1 ). The difference of their squares can be expressed as ( (n + 1)^2 - n^2 ), which simplifies to ( 2n + 1 ). Setting this equal to 25, we get the equation ( 2n + 1 = 25 ). Solving for ( n ), we find ( n = 12 ), so the two consecutive numbers are 12 and 13.

The difference of the squares of two consecutive odd numbers is 48What are the odd numbers?
The numbers are (x) and (x+2).Their squares are (x)2 and (x+2)2, or (x2) and (x2 + 4x + 4).The difference between the squares is (x2 + 4x + 4) - (x2) = 4x + 4 = 484x + 4 = 48x + 1 = 12x = 11 and (x + 2) = 13======================Check:112 = 121132 = 169169 - 121 = 48 yay!
