Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the number-pair that is different.
Answer & explanation
Correct answer: option 2
The logic followed here is :
8 : 34 → 8 × 4 + 2 = 34
5 : 24 → 5 × 4 + 2 = 22 ≠ 24 (odd)
6 : 26 → 6 × 4 + 2 = 26
7 : 30 → 7 × 4 + 2 = 30
