Find the missing term in the given series.
20 : 17 :: 104 : ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 59
The second number of each pair comes from the first by the same rule. In the first pair, 17 is half of 20, plus 7.
First pair: \(\frac{20}{2}+7=10+7=17\)
Second pair: \(\frac{104}{2}+7=52+7=59\)
