copying my answer from like 3 days ago,

 

The arithmetic mean of 10 consecutive even integers is 3. What is the least of these 10 even integers? If the mean is 3, then five of the numbers must be less than 3 and five greater than 3. The numbers less than 3 must be −6, −4, −2, 0, 2 and those greater than 3 must be 4, 6, 8, 10, and 12. The least of these is −6 .
