5 (divide 20 by 4)
30 (multiply 5 by 6)
6 ( divide 30 by 5)
42 (multiply 6 by 7)
7 (divide 42 by 6)
....as you can see the pattern switches from division to multiplication. From this pattern the next number will be mulitplying 7 by 8. so the next number is 56.
56 8 72 9 90 10 Divide by four, multiply by six, divide by five, multiply by seven... Divisors increase by one each time, as do the number multiplying by.
56 (just the next number, not the number that completes the sequence)

The number which best completes the sequence below is 20 5 30 6 42 7
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
