Only c. 24 is evenly divisible by 3
24/3 =- 8
4, 8, 12, 16, 20, 24, 28, 32, 36 . . . You can tell if a number is divisible by 4 by looking at the last two numbers, for example, is 1024 divisible by 4? To solve that, look at the last two numbers, 24. Is 24 divisible by 4? Yes, because 24 is a multiple of 4, so 1024 is divisible by 4!
Add numbers then divide total by amount of numbers So 14 16 has mid number of 15 as (14+16)/2 = 30/2 = 15 (as there are 2 numbers of 14 and 16) or 6 12 24 has mid number of 14 as (6+12+24)/3 = 42/3 = 14 (as there are 3 numbers of 6 and 12 and 24) and so on
18 - 16 = 2 14 / 2 = 7 17 + 7 = 24

100 ÷ 4 = 25 → 24 numbers between 0 and 100 exclusive are divisible by 4 100 ÷ 6 = 16 2/3 → 16 numbers between 0 and 100 are divisible by 6 lcm(4, 6) = 12 → 100 ÷ 12 = 8 1/3 → 8 numbers between 0 and 100 are divisible by 4 and 6.
All numbers in the 8x table. 8, 16, 24, 32, 40, 48, 56, 64... etc.
