integer .

Answer 1

Answer:

This is your answer. Please mark me as brainliest.

Step-by-step explanation:

On dividing n by 3, let q be the quotient and r be the remainder . Case I If n = 3q then n is clearly divisible by 3. Case II If n= ( 3q +1) then ( n+2) = (3q +3) = 3(q +1) , which is clearly divisible by 3. ... Hence, one and only one out of n,( n +1) and (n+2) is divisible by 3.
