Select the option that is related to the third number in the same way as the second number is related to the first number.
14 : 189 :: 22 : ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 473
In a number analogy, find the operation that turns the first number into the second, then apply the same operation to the third number. Here 189 is just below \(14^2=196\), so compare it with the square.
\(14^2=196\), and \(196-189=7\), which is half of 14
So the rule is: square the number and subtract half of it, \(14^2-7=189\)
For 22: \(22^2=484\), and half of 22 is 11
\(484-11=473\)
So the missing number is 473.
