MCQ
The common difference of the A.P. $\frac{1}{p}, \frac{1-p}{p}, \frac{1-2 p}{p}, \ldots$. is
- A$p$
- B$-p$
- ✓-1
- D1
✓
Answer
Correct option: C.
-1
(c) : Here, $a_1=\frac{1}{p}$ and $a_2=\frac{1-p}{p}$
$\therefore \quad$ Common difference $=a_2-a_1$
$
=\frac{1-p}{p}-\frac{1}{p}=\frac{1-p-1}{p}=\frac{-p}{p}=-1
$
$\therefore \quad$ Common difference $=a_2-a_1$
$
=\frac{1-p}{p}-\frac{1}{p}=\frac{1-p-1}{p}=\frac{-p}{p}=-1
