Answer:

$\frac{10 \times 5 {}^{n + 1} + 25 \times 5 {}^{n} }{3 \times 5 {}^{n + 2} + 10 \times 5 {}^{n + 1} } \\ = \frac{5 {}^{n}(10 \times 5 {}^{1} +25) }{5 {}^{n + 1} (3 \times 5 {}^{1} + 10) } \\ = \frac{5 {}^{n} \times 75}{5 {}^{n + 1} \times 25} \\ = \frac{ {5}^{n} \times 3}{5 {}^{n} \times 5 {}^{1} } \\ = \frac{3}{5} \: \: answer$
