Correct Answer: 2, 4, 5, 1, 3

Solution : Given:
1. Expensive 2. Expedition 3. Experience 4. Expel 5. Expenditure

Step 1: Compare the first letter of each word. Since all the words start with the same letter E , move on to the next letter.
Step 2: The second, third, and fourth letters of each word are the same x, p, and e , so move on to the next letter.
Step 3: The fifth letter of each word is: n, d, r, l, n . Based on the alphabetical order of these letters, we can arrange them – Expe d ition, Expe l, Expe n sive, Expe n diture, Expe r ience
Step 4: Compare the sixth letter of (Expen s ive, Expen d iture). Expenditure will come before Expensive in the sequence as d comes before s in the alphabetical system.

So, the sequence is Expedition, Expel, Expenditure, Expensive, Experience, or 2, 4, 5, 1, 3. Hence, the first option is correct.
