Answer 2

Step-by-step explanation:

Let n be any natural number.

then above equation can be written as..

n² + n

= n (n+1)

Now, if you take any number as n, then (n+1) will be the next number.

i.e, If u take n as even no. , then (n+1) will be an odd no. and vice versa.

We know by the property,

Odd number × Even No. = Even No.

and Even No. will always be divisible by 2.

so, n(n+1) will always divisible by 2 .
