Correct Answer: (10, 100)
Solution :
Let's check the options –
First option:
(8, 62); (8)
2
– 2 = 64 – 2 = 62
Second option:
(10, 100); (10)
2
– 2 = 100 – 2 = 98 ≠ 100
Third option:
(14, 194); (14)
2
– 2 = 196 – 2 = 194
Fourth option:
(12, 142); (12)
2

So, only the second option doesn't satisfy the pattern. Hence, the second option is correct.
