The number which best completes the sequence below is 20 5 30 6 42 7
If the sequence is 205, 306, 427 then a possible 4th number is 568. The initial difference between 205 and 306 is 101, which increases by 20 at each step. 306 → 427 = 121 : 427 → 568 = 141

A number sequence is not a question. So there can be no "answer".
20
10
The next number in the sequence 5, 10, 20, 40 is 80. Each number in the sequence is multiplied by 2 to get the next number. So, 40 multiplied by 2 equals 80.
The next number in the sequence will be 56.
320
To find the next number in the sequence 2, -6, 12, 4, 20, we can look for a pattern. The differences between consecutive numbers are -8, 18, -8, and 16, suggesting a pattern of alternating increases and decreases. Following this pattern, the next difference should be -8, so we subtract 8 from 20, giving us 12. Therefore, the next number in the sequence is 12.
