(24, 22, 264)

(17, 15, 220)

(9, 16, 170)

(15, 34, 190)

Let’s break this down. The set is (25, 18, 225). Look for the logic.

- First, think: Does the third number come from multiplying, adding, squares, or what?

- 25 - 18 = 7. That’s not matching 225.

- 25 × 18 = 450. Nope, not 225.

- Let’s check squares. 25 squared is 625, 18 squared is 324. Doesn’t fit.

- But hang on: 25 × 9 = 225. But where does 9 come from? Well, 18 / 2 = 9.

- So, the pattern is: First × (Second ÷ 2) = Third

Try that on option 1:

- 24 × (22 ÷ 2) = 24 × 11 = 264.

- Spot on!

Option 2: 17 × (15 ÷ 2) = 17 × 7.5 = 127.5. Not 220.

Option 3: 9 × (16 ÷ 2) = 9 × 8 = 72. Not 170.

Option 4: 15 × (34 ÷ 2) = 15 × 17 = 255. Not 190.

- Only option 1 follows the exact pattern.
