The multiples of 7 between 20 and 30 are calculated by finding the smallest multiple of 7 greater than 20 and the largest multiple of 7 less than 30. The smallest multiple of 7 greater than 20 is 21 (7 x 3) and the largest multiple of 7 less than 30 is 28 (7 x 4). Therefore, the multiples of 7 between 20 and 30 are 21, 28.

The larger numbers are multiples of the smaller numbers before and after. ... 4 20 5 30 6 42 7 56 ... 4 x 5 = 20 5 x 6 = 30 6 x 7 = 42 7 x 8 = 56 You can say it another way with division: 4 into 20 is 5, 5 into 30 is 6, 6 into 42 is 7, 7 into 56 is 8... (I just added the 4 and the 56 into the sequence to make the pattern easier to see. You can extend it in both directions.)
They are 21 and 28
