Find all pairs of consecutive odd natural numbers, both of which are larger than 10, such that their sum is less than 40.

Explanation

To solve the problem of finding all pairs of consecutive odd natural numbers, both larger than 10, such that their sum is less than 40, we can follow these steps:

### Step 1: Define the Variables
Let the smaller consecutive odd natural number be \( x \). The next consecutive odd natural number will then be \( x + 2 \).
