Answer 2

Answer:

The common difference is -1.

Step-by-step explanation:

Given:

The AP is $\sf \dfrac{1}{p} , \ \dfrac{1-p}{p} , \ \dfrac{1-2p}{p} .$

To Find:

The common difference of the AP.

Solution:

To find the common difference of the AP = ?

$\quad {\boxed{\bf Common \ difference \ = \ a_2 - a_1}}$

$\quad \longrightarrow \sf d = \bigg[ \dfrac{(1-p)}{p} \bigg] - \dfrac{1}{p}$

$\quad \longrightarrow \sf \dfrac{(1-p-1)}{p}$

$\quad \longrightarrow \sf \dfrac{-p}{p}$

$\quad \longrightarrow \sf -1$

$\therefore$ The common difference of the AP is -1.
