Question
Find, which of the following sequence from a G.P. :
8, 24, 72, 216,................
8, 24, 72, 216,................
✓
Answer
Given sequence: 8, 24, 72, 216,................
Now,
$\frac{24}{8}=3, \frac{72}{24}=3, \frac{216}{72}=3$
Since $\frac{24}{8}=\frac{72}{24}=\frac{216}{72}=\ldots \ldots . .=3$, the given sequence is a G.P. with common ratio 3.
Now,
$\frac{24}{8}=3, \frac{72}{24}=3, \frac{216}{72}=3$
Since $\frac{24}{8}=\frac{72}{24}=\frac{216}{72}=\ldots \ldots . .=3$, the given sequence is a G.P. with common ratio 3.
