$\underline\color{Green}{REAL\:NO}$


let n is be any positive integer 3q,3q+1and3q+2

then a+bq
let r =0
n=3q
thn 3q
it is clearly divisible by 3


case2

let r=1

thn
n= 3q+1
n+2=3q+3
n+2=3(q+1)

thn it is clearly divisible by 3

case3
let r =2
n=3q+2
n+1=3q+3
n+1=3(q+1)

thn it is clearly divisible by 3


hence one and only one of is divisible by 3
