Give an example of a relation which is transitive but neither reflexive nor symmetric.

Explanation

To provide a step-by-step solution to the question, we will define the terms involved, create a suitable set and relation, and then verify the properties of the relation.

### Step 1: Define the Properties of Relations
1. **Reflexive Relation**: A relation R on a set A is reflexive if for every element a in A, the pair (a, a) is in R.
2. **Symmetric Relation**: A relation R on a set A is symmetric if for every pair (a, b) in R, the pair (b, a) is also in R.
3. **Transitive Relation**: A relation R on a set A is transitive if whenever (a, b) and (b, c) are in R, then (a, c) must also be in R.

### Step 2: Define a Set
