Question

Select the option that is related to the fourth term in the same way as the first term is related to the second term.

13 : 196 :: 16 : ?

1. 289
2. 144
3. 121
4. 324

Answer 1

Correct Answer - Option 1 : 289

The number on the right of the colon is the square of the number that is one more than the number on the left of the colon.

13 : (13 + 1)² ⇒ 13 : 196
Similarly,
16 : (16 + 1)² ⇒ 16 : 289

Hence, 289 will come in place of the question mark.
