Question: If p, q, r are in Geometric Progression, then which is true among the following?
Options:
A) $ q=\frac{p+r}{2} $
B) $ p^{2}=qr $
C) $ q=\sqrt{pr} $
D) $ \frac{p}{r}=\frac{r}{q} $
Show Answer
Answer:
Correct Answer: C
Solution:
- Since, p, q, r, are in Geometric progression.
$ \therefore $ $ q^{2}=pr $
Then, $ q=\sqrt{pr}. $
