Question

What is the common ratio between successive terms in the sequence? 27, 9, 3, 1, one-third, one-ninth, StartFraction 1 over 27 EndFraction, ... –3 – 3

Answer 1

Answer:

$\frac{1}{3}$

Step-by-step explanation:

The given sequence is

$27, 9, 3, 1$

This sequences comprehend a geometric sequence, because it's obtained by dividing each element by 3, as follows

$\frac{27}{3}=9\\\\\frac{9}{3}=3\\ \\\frac{3}{3}=1$

Therefore, the reason is $\frac{1}{3}$, which consists in dividing each term by 3, it's the same if we multiply each term by $\frac{1}{3}$.

So, the right choice is the first option, one-third.

Answer 2

Answer:

One third.

Step-by-step explanation:

Common ratio = 9/27 = 1/3

3/9 = 1/3

1/3 = -/3.
