The sequence appears to be increasing at a variable rate. The pattern seems to be adding 1, then 3, then 5, then 10. Following this pattern, the next number in the sequence would be 20 + 15, which equals 35.

A number sequence is not a question. So there can be no "answer".
The next composite number after 20 is 21.
There are infinitely many possible answers. If the missing number is the second in the sequence, it could be part of an arithmetic progression and so equal 10.4, or it could be in geometric progression and so would be 4, or harmonic progression which would give 1/0.65 = 1.54, approx. Furthermore, he missing number cold be the first or third in the sequence.
I would make it 1 The above sequence is the numerical order of some of the numbers on a dart board
next in the sequence: 10,20,30,20
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.
10 is one possibility.
10
80
what number is next in the sequence: 10,20,30,20,(? 30
20
40 5 10 20 40 80 160.......double the number each time.
If you mean: 5 10 20 40 then it is 80
Double it every time and so the next number will be 80
The next number in the sequence would be 25.
