Identifying the Odd Pair in Number Sets
The question asks us to find the pair of numbers that is different from the others based on some underlying pattern or property. We need to examine each pair and look for a common characteristic shared by most pairs, but not by one.
Analyzing the Number Pairs
Let's look at the pairs provided:
- Pair 1: 13-17
- Pair 2: 24-28
- Pair 3: 19-23
- Pair 4: 29-31
Step-by-Step Pattern Identification
We can analyze the properties of the numbers within each pair:
-
Pair 1 (13-17):
- 13 is a prime number.
- 17 is a prime number.
- Both numbers in the pair are prime.
-
Pair 2 (24-28):
- 24 is a composite number (divisible by 1, 2, 3, 4, 6, 8, 12, 24).
- 28 is a composite number (divisible by 1, 2, 4, 7, 14, 28).
- Both numbers in the pair are composite.
-
Pair 3 (19-23):
- 19 is a prime number.
- 23 is a prime number.
- Both numbers in the pair are prime.
-
Pair 4 (29-31):
- 29 is a prime number.
- 31 is a prime number.
- Both numbers in the pair are prime.
Determining the Odd Pair
By examining the primality of the numbers:
- Pairs 1, 3, and 4 consist of two prime numbers each.
- Pair 2 consists of two composite numbers.
Therefore, the pair (24-28) is the odd one out because it is the only pair where both numbers are composite, while the other pairs consist solely of prime numbers.
