Question

The product of two consecutive natural numbers is always ________.

• A. An even number
• B. An odd number
• C. A prime number
• D. Divisible by 3

Answer 1

The correct option is A An even number

We know that amongst two consecutive natural numbers, one is even and one is odd.

Let even number be $2n$ and odd be $2n+1$

Their product gives $2n(2n+1)$ which is a multiple of $2$, hence it is an even number.
