Answer 6

Don't blame me if i misunderstood the question.

\[\frac{ 2*2^n }{ 2^n }\] - \[\frac{ n+2 }{ 2^n }\] + \[\frac{ \frac{ n}{ 2 } + \frac{ 1 }{ 2 } }{ 2^n }\]

=

\[\frac{ 2^{n+1} + 1.5 n + 2.5 }{ 2^n }\]

Answer 7

miscalculated it.

Answer 8

\[\frac{ 2^{n+1} - n - 2 + n/2 + 1/2 }{ 2^n }\]

Answer 9

No I think that 2^n+1=2^n*2 is with exponent rule so the 2^n I must multiplicate with 2.
so the exponent sums.
