The correct sequence according to dictionary order is: 1. Precede, 2. Precept, 3. Precise, 4. Precision, 5. Preach, 6. Prelude.
Explanation:
Dictionaries arrange words alphabetically, letter by letter. Since all the words start with the same letters “Pre”, we need to look at the next letter. “c” comes before “e”, “e” comes before “i”, “i” comes before “o”, and “o” comes before “r”. Therefore, the sequence is as listed above.
