Question : Directions: Select the option related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term.
4 : 18 :: 12 : ? :: 7 : 51
Option 1: 146
Option 2: 142
Option 3: 148
Option 4: 144
Correct Answer: 146
Solution :
Given:
4 : 18 :: 12 : ? :: 7 : 51
Add 2 to the square of the first number, to get the second number –
Like, 4 : 18→(4)
2
+ 2 = 16 + 2 = 18
And, 7 : 51→(7)
2
+ 2 = 49 + 2 = 51
Similarly, follow the same pattern for 12 : ?→(12)
2
+ 2 = 144 + 2 = 146
So, 146 is related to 12. Hence, the first option is correct.
