Answer:
The required expression is 4n+12.
Explanation:
Consider the provided information.
We need to write an expression for the sum of that number and the next three even numbers after it.
Let n represent an even integer.
The next three even numbers after it is:
First even number: n
The second even number: n+2
Third even number: n+4
Fourth even number: n+6
The sum of all even number is:
n+n+2+n+4+n+6
Add the like terms:
4n+6+6
4n+12
Hence, the required expression is 4n+12.
