Select the option in which the numbers are related in the same way as are the numbers of the following set.
(9, 21, 124)
Answer & explanation
Correct answer: option 4
(9, 21, 124)
The logic followed here is :
Ist number × 2 + 3 = IInd number
IInd number × 6 - 2 = IIIrd number
AS
9 × 2 + 3
= 18 +3
= 21
and
21 × 6 - 2
= 126 - 2 = 124
Similarly
(17, 37, 220)
17 × 2 + 3
= 34 +3
= 37
and
37 × 6 - 2
= 222 - 2 = 220
