The multiples of 6 between 1 and 40 are... 6, 12, 18, 24, 30 and 36
40 - 2*32 = 40-2*9 = 40 - 18 = 22
Not all multiples of 40 are multiples of 80. Only the even multiples of 40 are also multiples of 80. The odd multiples, e.g. 40, 120, 200, 280, and 360, are not multiples of 80.
12, 18, 24, 30 and 36.
There are six multiples of both 2 and 3 that fall between 1 and 40. They are: 6, 12, 18, 24, 30, 36.
First it adds by 3. Then on 4, 8, 12 it adds by 4. On 5 and 10 it adds by 5. So i guess it is 3, 4, 5.
The multiples of 24 are 24, 48, 72 and so on. The multiples of 40 are 40, 80, 120 and so on. The common multiples of 24 and 40 are 120, 240, 360 and so on.
