### The average of four consecutive even numbers is 15. The 2nd highest number is :

A. 12

B. 18

C. 14

D. 16

Let the four even consecutive numbers x, x + 2, x + 4, x + 6 According to the question, $\begin{array}{l}\left(\Large\frac{x+x+2+x+4+x+6}{4}\right)=15\\ x+12=60\\ x=48\\ c=12\\ \therefore\text{2nd highest number is }\\ x+4\\ 12+4\\ 16\end{array}$
