Answer 2

☆Your Answer ☆

I hope you mean

$25 {}^{n - 1} +100=5 {}^{2n - 1} </p><p>$

$⟹5 {?}^{2n - 2} +100=5 {}^{2n - 1} </p><p>$

$⟹\frac{52n−1}{5} +100=5 {}^{2n - 1} </p><p>$

$let \: 5 {}^{2n - 1} = t$

$so \: \frac{t}{5} + 100 = t$

$\frac{4t}{5} = 100$

$t = 125$

So we get,

$5 {}^{2n - 1} = {5}^{3}$

$2n - 1 = 3$

$2n = 4$

$n = 2$

so n = 2

hope this will help you....
