Question

Show that one and only one out of n, (n+2) or (n+4) is divisible by 3, where NEN.​

Answer 1

Let n = 1

● n = 1

● n + 2 = 1 + 2 = 3

● n + 4 = 1 + 4 = 5

■ Here (n + 2) is divisible by 3

In the same way only one of three is divisible by 3 when n is a natural number

Answer 2

Answer:

its n+2

Step-by-step explanation:

for example take n=1 then 1+2=3 ,3 is divisible by 3

if n= 4 ,,4+2=6 it is divisible by 3
