0, 1, 2 , 4, 6, 9, 12, 16 , ?
In order to find the missing number lets start the calculation as:
Now applying the reasoning method.
1 - 0 = 1
2 - 1 = 1
4 - 2 = 2
6 - 4 = 2
9 - 6 = 3
12 - 9 = 3
16 - 12 = 4
so, next term will be , x - 16 = 4
x = 16 + 4 = 20
Therefore the missing number is 20.

The number replacing the question mark is 20.
Explanation:
The pattern followed in solving the sequence is:
a - b = x
c - a = x
Where, b < a and a < c
Now, applying on the series, we get,
1 - 0 = 1
2 - 1 = 1
4 - 2 = 2
6 - 4 = 2
9 - 6 = 3
12 - 9 = 3
16 - 12 = 4
Now, finally,
x - 16 = 4
⇒ x = 4 + 16
∴ x = 20
