🔍 Clue Card #23:

> Clue #2: I am an odd number.
> Clue #3: I have a five in the ones place.
> Clue #4: I am one less than 26.

We’ll go step by step to deduce the mystery number.

---

✔ Step 1: Use Clue #1 — "I am between 20 – 29."

This means the number is:
> 20, 21, 22, 23, 24, 25, 26, 27, 28, or 29

---

✔ Step 2: Use Clue #2 — "I am an odd number."

Odd numbers in that range:
> 21, 23, 25, 27, 29

(We eliminate even numbers: 20, 22, 24, 26, 28)

---

✔ Step 3: Use Clue #3 — "I have a five in the ones place."

So, the digit in the ones place is 5.

From our remaining candidates (21, 23, 25, 27, 29), only 25 ends with 5.

So now we're down to:
> 25

---

✔ Step 4: Use Clue #4 — "I am one less than 26."

One less than 26 is:
> 26 - 1 = 25

✔ This matches!

All four clues are satisfied:
- Between 20–29 → ✔️
- Odd number → ✔️
- Has a 5 in the ones place → ✔️
