Question : 2 of 200

Marks: +1, -0

Select the option that is related to the third number in the same way as the second number is related to the first number.
13 ∶ 195 ∶∶ 18 ∶ ?

Solution:

The logic follows here is;

(\text "First Number "+ 1)^2 - 1 = \text "Second Number"

In 13 ∶ 195;

(13 + 1)^2 - 1

= 142 + 1

= 196 - 1

= 195

Similarly;
In 18 : ?;

(18 + 1)^2 - 1

= 192 - 1

= 361 - 1

= 360

Hence,"360" is the correct answer.
