WebReflexive Relation Examples. Example 1: A relation R is defined on the set of integers Z as aRb if and only if 2a + 5b is divisible by 7. Check if R is reflexive. Solution: For a ∈ Z, 2a + 5a = 7a which is clearly divisible by 7. ⇒ aRa. Since a is an arbitrary element of Z, therefore (a, a) ∈ R for all a ∈ Z.
