Question
Select the option that is related to the fourth number
in the same way as the first number is related to the second number and the fifth number is related to the sixth number. 18 : 328 :: ? : 148 :: 28 : 788Solution
18² + 4 = 324 + 4 = 328 28² + 4 = 784 + 4 = 788 Similarly, ?² + 4 = 148 ?² = 148 – 4 ?² = 144 ? = 12
