A number sequence is not a question. So there can be no "answer".
The next composite number after 20 is 21.
I would make it 1 The above sequence is the numerical order of some of the numbers on a dart board
20 over 10 is a whole number: 2
next in the sequence: 10,20,30,20
10
10 is one possibility.
80
10
what number is next in the sequence: 10,20,30,20,(? 30
20
If you mean: 5 10 20 40 then it is 80
40 5 10 20 40 80 160.......double the number each time.
Double it every time and so the next number will be 80
The next number in the sequence would be 25.
10 The sequence is given by xn = 60/n
