The relation (R={(a,b):a-b\text{ is even}}) is given on integers. What is it?

Answer and explanation

Correct answer: Symmetric

Step 1: If (a-b) is even, then (b-a=-(a-b)) is also even. Step 2: Therefore, whenever ((a,b)) satisfies the condition, ((b,a)) also satisfies it. Step 3: In parity questions, remember that the negative of an even number is also even.
