Select the option that is related to the third number in the same way as the second number is related to the first number.
28 : 625 :: 26 : ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 529
In a number analogy, find the operation that turns the first number into the second, then apply it to the third number. 625 is a perfect square, \(25^2\), and 25 is 3 less than 28.
\(28-3=25\), and \(25^2=625\), so the rule is: subtract 3 and square the result
For 26: \(26-3=23\)
\(23^2=529\)
So the missing number is 529.
