Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.
17 : 189 :: 13 : 69 :: 18 : ?
224
241
214
242
Let’s break it down step by step:
- 17 : 189
Take 17, multiply by 11, you get 187. But that’s not quite it.
Try squaring 17: 17² = 289. Not matching.
How about 17 × (17 + 1) = 17 × 18 = 306. Still off.
But wait: 189 / 17 ˜ 11.118. Not perfect.
Let’s try 17 × 11 + 2 = 189. Bingo.
- 13 : 69
Now, 13 × 5 + 4 = 69.
- The jump in logic here is unclear. Let’s check another pattern:
Maybe 17 × (some number) + (small number) = 189
So: 189 - 17 = 172. 172 / 17 = 10.117. No clean number.
- Try factor pairs—189 / 13 = 14.538. Nope.
So let's lay the pairs out:
- 17 : 189 (189 = 17 × 11 + 2)
- 13 : 69 (69 = 13 × 5 + 4)
If we try 18,
- Option 1: 224 ? 224 / 18 = 12.44
- Option 2: 241 ? 241 / 18 = 13.39
- Option 3: 214 ? 214 / 18 = 11.88
- Option 4: 242 ? 242 / 18 = 13.44
But let's check each option by squaring:
- 18² = 324
No option is close.
Let’s try 18 × (close integer) + (small number) to see if the logic fits.
From 17 : 189, difference is 172 (189-17),
From 13 : 69, difference is 56 (69-13).
Still, there’s no clear, consistent pattern.
But if you check the options, nothing fits a clear, unique formula from the first two pairs.
Here’s the thing—this is a tough pattern, but from logic, none of the options clearly matches anything used above.
