To find the missing number in the sequence, let's analyze the pattern. This sequence appears to be formed by adding 1, then 3, then 5, and so on, increasing the difference by 2 each time.

Here's a breakdown of the differences:

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

Following this pattern, the next difference should be 9. So, the missing number in the sequence would be:

16 + 9 = 25

Therefore, the complete sequence is:

0, 1, 4, 9, 16, 25
