Select the option that is related to the third number in the same way as the second number is related to the first number.
31 : 900 :: 34 : ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 1089
900 is a perfect square, \(30^2\), and 30 is one less than 31. So the rule is: subtract 1 and square.
\(31-1=30\), and \(30^2=900\)
For 34: \(34-1=33\)
\(33^2=1089\)
So the missing number is 1089.
