Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Response:
25

To find the missing number in the sequence, let's analyze the pattern:

- 0 + 1 = 1
- 1 + 3 = 4
- 4 + 5 = 9
- 9 + 7 = 16

The pattern appears to be adding consecutive odd numbers. 

So, the next odd number to add would be 11 (since 7 + 4 = 11), making the next number in the sequence: 16 + 11 = 27.

Therefore, the missing number in the sequence is 27.
