840, 1680, 2520 and so on.
They are 24 and 28.
The set is: 20, 24, 28.
24, 28, 32, 36.
The multiples of 4 that are less than 30 are 4, 8, 12, 16, 20, 24, 28
4, 8, 12, 16, 20, 24, 28...
The multiples of 4 that are under 28 are 4, 8, 12, 16, 20, 24, 28
The multiples of 4 between 20 and 40 are 24, 28, 32, and 36.
The first seven multiples of 4 are 4, 8, 12, 16, 20, 24, and 28.
1, 2, 4, 7, 24 and 28 are all the multiples of 28
4, 8, 12, 16, 20, 24, 28, 32.
4, 8, 12, 16, 20, 24, 28
The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48. The multiples of 6 are 6, 12, 18, 24, 30, 36, 42, and 48. Thus, the multiples of 4 that are not multiples of 6 are 4, 8, 16, 20, 28, 32, 40, and 44.
