Explanation:

- Let's denote the four consecutive even numbers as $x,x+2,x+4,x+6$.

- The average of the last and the first numbers is given as 11:

$(x+6+x)/2=11$.

- Simplifying this, we get $2x+6=22$.

- So, $2x=16$, and thus $x=8$.

- The numbers are 8, 10, 12, and 14.

- The second number is 10 and the third number is 12.

- The difference between the second and third numbers is $12-10=2$.
