On the set of integers, the relation (R={(a,b):a-b\text{ is even}}) is given. Is (R) transitive?

Answer and explanation

Correct answer: Yes

Step 1: If (a-b) is even and (b-c) is even, then their sum ((a-b)+(b-c)=a-c) is also even. Step 2: Hence ((a,c)) belongs to (R), so the relation is transitive. Step 3: In such questions, add the given differences.
