Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.

16 : 128 :: 18 : 162 :: 22 : ?

242

16 : 128 :: 18 : 162 :: 22 : ?

The logic followed here is :

Ist number × Half of ist number = IInd number

As

16 × 8 = 128

And

18 × 9 = 162

Similarly

22 × 11 = 242
