56
In the sequence 20 5 30 6 42 7, the rule is divide by 4 then multiply by 6, divide by 5 then multiply by 7, divide by 6 then multiply by 8 since each time the number by which you multiply or divide by increases by 1. Since the last multiplication was by 7, we know the next will be by 8. Therefore, the answer you get for the next number in the sequence is 56 (7x8=56).
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
The next number in the sequence will be 56.

75
30% of 42= 30% * 42= 0.3 * 42= 12.6
56
20 5 30 6 42 7 Every other number is the product (multiplied) of the numbers it is between(5x6=30, 6x7=42), and the numbers between go in order (5, 6, 7) Therefor the next #s would be 56 8 72 9 90 10
56 (just the next number, not the number that completes the sequence)
The least common factor of 30 and 42 is the smallest number that is a factor of both of them and is 1.However, I suspect that you mean either:What is the highest common factor of 30 and 42?ie what is the highest number that is a factor of both 30 and 42: hcf = 6;What is the lowest common multiple of 30 and 42?ie that is the smallest number that is a multiple of both 30 and 42 lcm = 210.
