Lets check each option:
1) 12 ∶ 156
⇒ 12 × (12 + 1) = 12 × 13 = 156
⇒ This pair follows the logic.
2) 15 ∶ 240
⇒ 15 × (15 + 1) = 15 × 16 = 240
⇒ This pair follows the logic.
3) 14 ∶ 210
⇒ 14 × (14 + 1) = 14 × 15 = 210
⇒ This pair follows the logic.
4) 21 ∶ 468
⇒ 21 × (21 + 1) = 21 × 22 = 462
⇒ This pair does not follow the logic.
21 : 468 is the odd one out.
Hence, 'option 4' is the correct answer.
