Practicing Success
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. 21 : 529 :: 25 : 729 :: 17 : ? |
441 289 324 361 |
361 |
21 : 529 :: 25 : 729 :: 17 : ? The logic; 21 : 529 21 +2= 23 \( {23 }^{2 } \) = 529 And, 25 : 729 25 +2= 27 \( {25}^{2 } \) = 729 Similarly, 17 : ? 17 +2= 19 \( {19}^{2 } \) = 361
