f[n_]:= -(-1)^n*(2^n-n);
Sum[f[n],{n,0,5}]

I'm concerned whether your Sum should begin with n==0 or n==1 when I read the text of your description.

You can look at the individual terms with

Table[f[n],{n,0,5}]

to make certain that you have this correct before you use the Sum and wonder why the result might not be correct
