find the odd man out 16, 25, 36, 72, 144, 196, 225

  1. 36

  2. 72

  3. 196

  4. 225


Correct Option: B

AI Explanation

To find the odd one out in the given sequence 16, 25, 36, 72, 144, 196, 225, we need to look for a pattern or rule that applies to most of the numbers in the sequence but not to the odd one out.

Let's analyze the given sequence:

16: 4^2 25: 5^2 36: 6^2 72: 8^2 + 8 (odd one out) 144: 12^2 196: 14^2 225: 15^2

As we can see, most of the numbers in the sequence are perfect squares, except for 72. Therefore, the odd one out in the given sequence is 72 (option B) because it does not follow the pattern of being a perfect square.

Hence, the correct answer is B.
