Answer 1

Answer:

I don't know this answer sorry

Answer 2

Given:

$\bold{25, -5, 1, \frac{-1}{5}}$

To Find:

Common ratio:

Solution:

Given series:

⇒ $\bold{25, -5, 1, \frac{-1}{5}}$

In the given series in G.P. So, the formula of common difference:

$\to \ common \ difference = \frac{\ second \ term}{\ first \ term}$

$a_1= 25\\\\a_2=-5\\\\a_3=1\\\\a_4=\frac{-1}{5}$

Common differences are as follows:

$\to \ Common \ difference \ (r_1) = \frac{a_2}{a_1}$

                                               $= \frac{-5}{25}\\\\= - \frac{1}{5}$

$\to \ Common \ difference \ (r_2)= \frac{a_3}{a_2}$

                                               $= \frac{1}{-5}\\\\= - \frac{1}{5}$

So, the common difference is = $\bold{-\frac{1}{5}}$
