```
This code defines a function `tri` that takes an integer `n` as input. It initializes a list `sequence` with the first two numbers of the Tribonacci sequence (1 and 3). Then, it uses a for loop to generate the next `n - 1` numbers of the sequence. If the current number `i` is even, it appends `1 + i / 2` to the sequence. If `i` is odd, it appends the sum of the last three numbers in the sequence to the sequence. Finally, it returns the sequence.

The function `tri` takes a non-negative integer `n` as input and returns a list of the first `n + 1` numbers of the Tribonacci sequence. The function first checks if `n` is equal to 1 or 2, in which case it returns the appropriate list. For `n` greater than 2, the function initializes a list `tri_list` with the first two numbers of the sequence, and then iterates over the remaining numbers of the sequence using a `for` loop. For even numbers of `i`, the function appends `1 + i // 2` to `tri_list`. For odd numbers of `i`, the function appends the sum of the previous three numbers of the sequence to `tri_list`. Finally, the function appends the sum of the last three numbers of the sequence to `tri_list` to complete the sequence. The function returns the completed `tri_list`.

Explanation:
The function `tri` takes an integer `n` as input and returns a list of the first `n+1` numbers of the Tribonacci sequence. The Tribonacci sequence is defined by the recurrence relation `tri(n) = 1 + n / 2` if `n` is even, and `tri(n) = tri(n-1) + tri(n-2) + tri(n+1)` if `n` is odd.

The function first checks if `n` is 0, 1, or 2, and returns the corresponding list of the first `n+1` numbers of the Tribonacci sequence. If `n` is greater than 2, the function initializes a list `sequence` with the first three numbers of the sequence (1, 3, 2). It then iterates over the range from 3 to `n+1`, and for each `i`, it checks if `i` is even or odd. If `i` is even, it appends `1 + i // 2` to the list. If `i` is odd, it appends the sum of the previous three numbers in the sequence to the list. Finally, the function returns the `sequence` list.

    sequence.append(1 + n / 2)

    return sequence
```

This code defines a function `tri` that takes a non-negative integer `n` as input and returns a list of the first `n + 1` numbers of the Tribonacci sequence. The function first initializes the sequence with the first element `3`. Then, it checks if `n` is `0` or `1` and returns the sequence accordingly. For `n` greater than `1`, it iterates from `2` to `n` and appends the appropriate value to the sequence based on whether `i` is even or odd. Finally, it returns the complete sequence.
