10 is one possibility.
next in the sequence: 10,20,30,20
10
10
80
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
The next number in the sequence will be 56.
