Risolvi Q=frac{16*4^{n-2}+45*4^{n+1}-4^n+2}{12*2^2n-1+25*2^2n+1-15*2^2n+2}

$$Q = \frac { 16 \cdot 4 ^ { n - 2 } + 45 \cdot 4 ^ { n + 1 } - 4 ^ { n + 2 } } { 12 \cdot 2 ^ { 2 n - 1 } + 25 \cdot 2 ^ { 2 n + 1 } - 15 \cdot 2 ^ { 2 n + 2 } }$$

Trova Q

$$Q = -\frac{165}{4} = -41\frac{1}{4} = -41,25$$

Trova n

$$n\in \mathrm{R}$$

$$Q = -\frac{165}{4} = -41\frac{1}{4} = -41,25$$
