Final answer:
A document may be missing in a sequence check due to various reasons: it was never created or recorded, it was lost or misplaced, or there was an error or omission when recording it in the sequence.
Step-by-step explanation:
A document may be missing in a sequence check due to various reasons:
- If the document was never created or recorded in the first place, it will be missing from the sequence.
- If the document was lost or misplaced during the sequence check process, it will not be found.
- If there was an error or omission when recording the document in the sequence, it may be mistakenly missing from the sequence check.
It is important to review the entire sequence check process and analyze each step to identify the possible reasons for a missing document.
