Correct Answer: 12 – 50

Solution : Let's check the options –
First option: 12 – 50; 12 × 4 = 48; 48 + 4 = 52 ≠ 52
Second option: 8 – 36; 8 × 4 = 32; 32 + 4 = 36
Third option: 10 – 44; 10 × 4 = 40; 40 + 4 = 44
Fourth option: 18 – 76; 18 × 4 = 72; 72 + 4 = 76

So, only the first option does not follow the same logic as followed by the other three options. Hence, the first option is correct.

Correct Answer: 1009 – 1018091

Solution : Let's check each option –
First option: (1003 – 1006009); 1003² = 1006009
Second option: (1009 – 1018091); 1009² = 1018081 ≠ 1018091
Third option: (1007 – 1014049); 1007² = 1014049
Fourth option: (1001 – 1002001); 1001² = 1002001

So, only the second option is different from the others. Hence, the second option is correct.

Correct Answer: 22 – 40

Solution : Let's check each option –

Third option: (18 – 35); (18 × 2) – 1 = 36 –​​​​​​​ 1 = 35
Fourth option: (16 – 31); (16 × 2) – 1 = 32 –​​​​​​​ 1 = 31

So, only the first option doesn't follow the same pattern as followed by the given set of numbers. Hence, the first option is correct.
