Select the option in which the numbers are related in the same way as are the numbers of the following set.
(12, 30, 61)
Answer & explanation
Correct answer: option 4
(12, 30, 61)
The logic followed here is :
(12 × 2) + (12 ÷ 2) = 24 + 6 = 30
30 × 2 + 1 = 60 + 1 = 61
Similarly
(18, 45, 91)
(18 × 2) + (18 ÷ 2) = 36 +9 = 45
45 × 2 + 1 = 90 + 1 = 91
