Averaging Columns of Information

Question:
How do I get the average of three columns for each row of a table that has four columns of information?

Answer:
Let's say you have a table called Test with four columns like this:

ID  Col1  Col2  Col3

1    10    20    20
This SELECT statement will return an average value for Col1, Col2 and Col3:
SELECT ((Col1+Col2+Col3)/3) AS ColAvg FROM Test


ColAvg                       
---------------------------- 
16.666666
