Final answer:

The number being described in the riddle is x, which remains unchanged after being doubled, tripled, and then divided by 6. This is because these operations are inverse operations, canceling each other out and returning the original number.

Step-by-step explanation:

Let's solve the riddle step-by-step to find out what number is being described. First, we need to identify the unknown number, which we can call 'x'.

Double me: 2x.

Multiply by 3: 6x.

Divide by 6: x.

The last step tells us that after these operations, we have the original number once more, which confirms that 'x' is indeed the solution to the riddle. The operations cancel each other out because multiplying by 3 and then dividing by the same number (6) gets you back to the original number.

The number we are looking for does not change through these operations, demonstrating an important property in mathematics: the inverse relationship between multiplication and division.
