In the following question, select the related number from the given alternatives.
14 : 197 :: 18 : ?
The logic here is
14$$^2$$ + 1 = 197
Sum of square of first number and 1 is equal to the second number.
Similarly,
The required number = 18$$^2$$ + 1 = 325
$$\therefore\ $$325 is related to 18 in the same way 197 is related to 14.
