Exists[f[i], i \[Element] Integers, 100 <= f[i] < 0]


While not wishing to be unkind or discouraging, may I suggest that, rather  
than repeatedly asking for the code necessary to solve a given problem,  
you instead focus on specifying your problems correctly to start with? So  
far all three of the problems you have asked about have been misstated, as  
well as being very similar to one another such that one wonders if you are  
really asking for help in good faith or just hoping for someone to solve  
your problem for you.
