Question 17

In the following question, select the odd number from the given alternatives.

Solution

The logic here is

12$$^2$$ + 12 = 144 + 12 = 156

13$$^2$$ + 13 = 169 + 13 = 182

14$$^2$$ + 14 = 196 + 14 = 210

15$$^2$$ + 15 = 225 + 15 = 240

Second number is the sum of first number and square of first number.

$$\therefore\$$15 - 230 is the odd one among the given number pairs.

Hence, the correct answer is Option D
