Determining Dictionary Order

To find the correct dictionary order, we compare the given words letter by letter, starting from the first letter.

Comparative Analysis of Words

The words provided are:

• 1. track
• 2. trace
• 3. trade
• 4. treasure
• 5. triangle

Step 1: Initial Letter Comparison

All five words start with the prefix 'tra'. Therefore, we must examine the letters that follow this common prefix to determine the order.

Step 2: Fourth Letter Comparison

We compare the fourth letter of each word:

• track: 'c'
• trace: 'c'
• trade: 'd'
• treasure: 'e'
• triangle: 'i'

Alphabetically, 'c' comes before 'd', 'd' before 'e', and 'e' before 'i'. This means the words starting with 'trac' will come first, followed by the word starting 'trad', then 'trea', and finally 'tri'.

Step 3: Ordering Words with 'trac' Prefix

We need to determine the order between track and trace, as both share the 'trac' prefix.

Compare the fifth letters:

• track has 'k'.
• trace has 'e'.

Since 'e' comes before 'k' in the alphabet, trace (2) precedes track (1) in dictionary order.

Step 4: Establishing the Full Sequence

Combining the comparisons:

1. The 'trac' words come first: trace (2), then track (1).
2. Next comes the word with 'd' as the fourth letter: trade (3).
3. Following that is the word with 'e' as the fourth letter: treasure (4).
4. The last word is the one with 'i' as the fourth letter: triangle (5).

The complete dictionary order is: trace, track, trade, treasure, triangle.

Final Number Sequence

The correct order using the original numbering of the words is 2, 1, 3, 4, 5.
