The number which best completes the sequence below is 20 5 30 6 42 7
The next number in the sequence will be 56.

20 5 30 6 42 7 56 8............... 4*5=20 5*6=30 6*7=42 7*8=56

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.)
