Question
Select the option that is related to the third term in
the same way as the second term is related to first term and the sixth term is related to the fifth term. 80: 728 :: 63: ? :: 35: 216Solution
The logic followed here is: The first number is one less than the square of a number (n) and the 2nd number is one less than the cube of a number (n). 80: 728 = 9² - 1 = 80, 9³ - 1 = 728 35: 216 = 6² - 1 = 35, 6³ - 1 = 215 63: 511 = 8² - 1 = 63, 8³ - 1 = 511
