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

### Response:
25
assistant

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 seems to be adding consecutive odd numbers. 

So, the next number in the sequence should be:
16 + 9 = 25

Therefore, the missing number is 25.
