Which of the following is a technique used to determine if a key number field in the record is in the correct ascending testing for duplicate transactions fuzzy matching Benford's Law sequence check

The technique used to determine if a key number field in the record is in the correct ascending order is called a **sequence check**. This method verifies that the values in a specific field follow a logical sequence, which helps identify any missing or duplicate entries. The other options mentioned serve different purposes: - **Testing for duplicate transactions** focuses on identifying repeated entries. - **Fuzzy matching** is used to find records that are similar but not identical, often used in data cleaning. - **Benford's Law** is a statistical principle that predicts the frequency distribution of the first digits in numerical data. So, the correct answer is **sequence check**.
