Correct Answer: 5 – 47
Solution :
Let's check the options –
First option:
7 – 81→(7 + 2)
2
= (9)
2
= 81
Second option:
9 – 121→(9 + 2)
2
= (11)
2
= 121
Third option:
11 – 169→(11 + 2)
2
= (13)
2
= 169
Fourth option:
5 – 47→(5 + 2)
2
= (7)
2
= 49
≠ 47
So, the fourth option does not follow the pattern. Hence, the fourth option is correct.
