Select the option that is related to the fourth term in the same way as the first term is related to the second term and the fifth term is related to the sixth term

5 : 7 :: ? : 271 :: 22 : 466

17

5 : 7 :: ? : 271 :: 22 : 466

The logic Followed here is

Ist number² - 18 = IInd number

As

5 : 7

5² - 18

25 - 18 = 7

And

22 : 466

22² - 18

484 - 18 = 466

Similarly

? : 271

X² - 18 = 271

X² = 271 +  18

X² = 289

X = 17  (because 289 is perfect square of 17)
