x+6-x=6

the answer is 6

Answer 2

Step-by-step explanation:

Let the four consecutive even numbers be 2x-2, 2x, 2x+2 and 2x+4 respectively.

We know that average is the sum of all terms divided by the total number of terms.

So, the difference between the first and the last numbers are (2x+4)-(2x-2) = 2x+4-2x+2 = 4+2 =6.

Hence, difference is 6.
