Select the set in which the numbers are related in the same way as are the numbers of the following sets.

(30, 14, 8)
(84, 12, 36)

(108, 18, 45)

(30, 14, 8)
(84, 12, 36)

The logic followed here is :

(Ist number - second number) ÷ 2 = IIIrd number

As

(30 - 14) ÷ 2

16 ÷ 2  = 8

and

(84 - 12) ÷ 2

72 ÷ 2  = 36

Similarly

(108, 18, 45)

(108 - 18) ÷ 2

90 ÷ 2  = 45
