On (A={1,2,3,4,5}), the relation (R={(1,2),(2,5),(1,5),(3,4)}) is given. Is this relation transitive?

Answer and explanation

Correct answer: It is transitive

Step 1: In transitivity, check only pairs where the second element of the first pair matches the first element of the next pair. Step 2: Here ((1,2)) and ((2,5)) require ((1,5)), which is present. After ((3,4)), no pair starts with (4). Step 3: Do not treat every missing self-pair as an error; check only required chains.
