This Answer Will Help You.Then Mark It As A Brainliest Answer.Thanks.

Step-by-step explanation:

if I Take 1 In The Place Of n Then,

n= 1

n+1= 1+1= 2

n+2= 1+2= 3

here Only One Is Divisible By 3.

Same As Above we can Take 2At The place of n Then,

n= 2

n+1= 2+1= 3

n+2= 2+2= 4

Here Again only One Is Divisible.

This Will Happen Again And Again Because 3 Is A Odd No.
