Find the missing term:
31 : 961 : : ? : 1369
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 37
In the first pair, the second number is the square of the first: \(31^2=961\). So the missing number is the number whose square is 1369.
\(1369\) ends in 9, so its square root ends in 3 or 7
\(37^2=1369\)
