Answer 2

Given:

A set of numbers 1, 4, 9, 16, 23, 25, and 36.

To Find:

The odd term in the given set of numbers is?

Solution:

1. The given set of numbers are 1, 4, 9, 16, 23, 25, and 36.

2. Consider the given set of numbers:

• 1 is a perfect square number. The number 1 can be also written as 1². Hence 1 is a perfect square number.

• 4 is a perfect square number. The number 4 can be also written as 2². Hence 4 is a perfect square number.
• 9 is a perfect square number. The number 9 can be also written as 3². Hence 9 is a perfect square number.
• 16 is a perfect square number. The number 16 can be also written as 4². Hence 16 is a perfect square number.
• 25 is a perfect square number. The number 25 can be also written as 5². Hence 25 is a perfect square number.
• 36 is a perfect square number. The number 36 can be also written as 6². Hence 36 is a perfect square number.
• 23 is not a perfect square number. The number 23 cannot be also written in the form of a². Hence 23 is a not perfect square number.

3. In the given set of numbers all the numbers except 23 are perfect squares. Hence the odd term is 23.

Therefore, the odd term in the given series is 23.
