Select the option that is 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.
13 : 69 :: 17 : ? :: 23 : 129
Answer & explanation
Correct answer: option 2
The logic followed here is:
Second number = (First number × 6) - 9
13 : 69 → (13 × 6) - 9 =78 - 9 = 69
23 : 129 → (23 × 6) - 9 =138 - 9 = 129
Similarly,
17 : ? → (17 × 6) - 9 =102 - 9 = 93
Hence, 93 is the correct answer .
