Select the option in which the numbers are related in the same way as are the numbers of the following set.
(57, 126, 199)
Answer & explanation
Correct answer: option 3
(57, 126, 199)
The logic followed here is :
(Ist number + IIIrd number)÷2 -2 = IInd number
as
(57 +199) ÷ 2 - 2
256 ÷ 2 - 2
128 - 2
126
Same as (63, 132, 205)
(63 + 205) ÷ 2 - 2
268 ÷ 2 - 2
134 - 2 = 132
