Step-by-step explanation:
I wouls say to my friend that he is incorrect, because there are infinitely many pairs of numbers with a difference of 12.
For example,
[tex]13-1=12\\ 14-2=12\\15-3=12\\16-4=12\\...[/tex]
Here we can increase the first and the second number by 1 and get their difference equal to 12 after this operation.
The same is possible with negative numbers:
[tex]-1-(-13)=12\\ -2-(-14)=12\\-3-(-15)=12\\ ...[/tex]
Actuall, we can do this with decimals too
[tex]12.5-0.5=12\\ \\13.4-1.4=12\\ \\12\dfrac{1}{8}-\dfrac{1}{8}=12\\...[/tex]
Such pairs of numbers are infinitely many (because there are infinitely many real numbers) and we cannot find all possible numbers with difference of 12.
