Answer 1

$\frac{ {5}^{ n+ 3} - 16 \times {5}^{n + 1} }{12 \times {5}^{n} - 2 \times {5}^{ n+ 1} } \\ = > \frac{{5}^{n}( {5}^{ 3} - 16 \times {5}^{ 1} ) }{{5}^{n}(12 \times - 2 \times {5}^{1} )} \\ = > \frac{( {5}^{ 3} - 16 \times {5}^{ 1} ) }{(12 \times - 2 \times {5}^{1} )} \\ = > \frac{125 - 80}{12 - 10} \\ = > \frac{45}{2} \\ = > 22 \frac{1}{2}$

hope it helps you
