Question : Directions: Select the option that is related to the fourth term in the same way as the first term is related to the second term and the fifth term is related to the sixth term.
7 : 40 :: ? : 667 :: 39 : 1512
Option 1: 34
Option 2: 25
Option 3: 47
Option 4: 26
Correct Answer: 26
Solution :
Given:
7: 40:: ?: 667:: 39: 1512
Subtract 9 from the square of the first term to get the second number –
Like in, 7 : 40→7
2
– 9 = 40
And in, 39 : 1512→39
2
– 9 = 1512
Similarly, follow the same pattern for ? : 667→X
2
– 9 = 667⇒X
2
= 676⇒X = 26
So, 26 is the required missing term. Hence, the fourth option is correct.
