Do merely evaluates its expression it does not produce any output separate from what the expression does. Or as the help for Do states: Unless an explicit Return is used, the value returned by Do is Null. Use Table
Table[Select[{1, 2, 4, 7, 6, 2}, # >= i &], {i, 7}]
{{1,2,4,7,6,2},{2,4,7,6,2},{4,7,6},{4,7,6},{7,6},{7,6},{7}}

Hi!
Can anybody tell, why
Do[Select[{1, 2, 4, 7, 6, 2}, # >= i &], {i, 7}]
does not produce output in Mathematica?
