The correct answer is

35

Understanding the Odd One Out in Number Series

The question asks us to identify the 'odd one out' from the given options, based on the characteristics of the numbers presented in the list: 3, 29, 35, 41, 47, 53. We need to find a pattern or property that most numbers share, and one number (or option) does not.

Analyzing the List of Numbers (3, 29, 35, 41, 47, 53)

Let's examine the properties of each number in the list:

  • 3: This is a prime number. It is only divisible by 1 and 3.
  • 29: This is a prime number. It is only divisible by 1 and 29.
  • 35: This is a composite number. It is divisible by 1, 5, 7, and 35. We can write it as \(35 = 5 \times 7\).
  • 41: This is a prime number. It is only divisible by 1 and 41.
  • 47: This is a prime number. It is only divisible by 1 and 47.
  • 53: This is a prime number. It is only divisible by 1 and 53.

From this analysis, we see that within the list 3, 29, 35, 41, 47, 53, all numbers except 35 are prime numbers. 35 is the only composite number.

Analyzing the Given Options (41, 23, 35, 29)

Now let's look at the options provided and check their properties, specifically focusing on whether they are prime or composite, as this was the pattern observed in the list.

  • 41: This is a prime number (divisible only by 1 and 41).
  • 23: This is a prime number (divisible only by 1 and 23).
  • 35: This is a composite number (divisible by 1, 5, 7, and 35). \(35 = 5 \times 7\).
  • 29: This is a prime number (divisible only by 1 and 29).

Identifying the Odd One Out

Comparing the options, we find that three of the options (41, 23, and 29) are prime numbers. The number 35, however, is a composite number. Therefore, based on the property of being prime or composite, 35 is different from the other options.

The number 35 is the odd one out because it is a composite number, while the other numbers in the list (3, 29, 41, 47, 53) and most of the options (41, 23, 29) are prime numbers.

Thus, the odd one out among the given options is 35.
