Answer:
14
Step-by-step explanation:
multiples are the list of number that can be multiplied by a certain number.
list the multiples
make a chart
1 × 7 = 7 (odd)
2 × 7 = 14 (even)
the first even multiple is 14 (2×7)
Answer:
The set of natural numbers can be denoted as: {} (null set) because no natural number will satisfy the given equation.
Step-by-step explanation:
Given equation:

To find the set of natural numbers that satisfies the above equation.
Solution:
In order to find the set of solutions for the equation, we will solve it for 
We have:

Subtracting both sides by 8.

∴ 
Thus, we get only one solution for
that satisfies the given equation but it is not a natural number. -3 is an integer.
Set of natural numbers {1,2,3,4,5,6........}
Thus, we can say the set of natural numbers that satisfies the equation is a null set {}.
