I was trying to answer the following question: What is the arithmetic mean of the following numbers?

8,6,8,2,8,7,4

All the numbers added equals 43
If I divide with 7, I receive the answer of 6.14. The system is telling me I am wrong. Well...ultimately the question is, what am I doing wrong or is there a glitch?
