Why are all the multiples of eight also multiples of four

♥ 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104 and so on.
♥ All you need to do is add 8 each time, and that answer is a multiple. 
♥ Same goes for 4, add 4 to it. 
♥ 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100
♥ and once again go on.
♥ Since 8 is half of 4 the answer will resemble what the multiples are. 

In my opinión this is the first person
