The pair of numbers that have the greatest common factor of 3 are:
6 and 9
18 and 15
3 and 9
<h3>What is
greatest common factor?</h3>
The biggest number, which is the variable of at least two number is known as the Best Normal Element (GCF). It is the biggest number (factor) that partition them bringing about a Characteristic number. When every one of the elements of the number are found, there are not many variables which are normal in both.
The factors of 6 and 9 are:
6 ⇒ 1, 2, 3 and 6
9 ⇒ 1, 3, 9
The greatest common factor here is therefore 3.
The factors of 18 and 15 are:
18 ⇒ 1, 2, 3, 6, 9 and 18
15 ⇒ 1, 3, 5, and 15
Greatest common factor is also 3
The factors of 3 and 9 are:
3 ⇒ 1 and 3
9 ⇒ 1, 3, 9
Greatest common factor here is also 3.

Answer:
Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
Step-by-step explanation:
Let X=set of all odd numbers
that is
Let Y=set of all even numbers
that is
Verify that 2(n+1) represents an even number where n is an odd number:
Put n=1 in 2(n+1) we get
2(1+1)=2(2)=4
Put n=3 in 2(n+1) we get
2(3+1)=2(4)=8
Put n=5 in 2(n+1) we get
2(5+1)=2(6)=12
and so on.
From above results we get 2(n+1) represents an even number and is belongs to the set Y when n is an odd number.
Therefore Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
