The difference between the squares of two consecutive numbers is the sum of those two numbers.
For example:
2 squared is 4.
3 squared is 9.
9-4=5
2+3=5
This is for a very simple reason:
To go from 2x2 or '2 lots of two' to '3 lots of two' (3x2) we must add another two.
3 lots of two equals 2 lots of three. To get to three lots of two we need another three. We have added two then three, or 2+3.
You can also apply this rule two numbers further apart, but to discover their squares' difference you must add them together and multiply by their difference
EG. 2 squared is 4
4 squared is 16
16-4= 12
(2+4)x2=12
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.
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}

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 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!
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

16,25,36 add to 77. They are the squares of consecutive numbers 4,5,6
Just check the squares of a few whole numbers. If 55 is between two of those squares, then its square root is also between the corresponding square roots.
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!
