Question

What is the common ratio for the sequence 54, 18, 6, 2, …? 3 -3

Answer 1

Answer:

r = $\frac{1}{3}$

Step-by-step explanation:

Calculate the ratio between consecutive terms, that is

$\frac{18}{54}$ = $\frac{1}{3}$

$\frac{6}{18}$ = $\frac{1}{3}$

$\frac{2}{6}$ = $\frac{1}{3}$

Thus the common ratio r = $\frac{1}{3}$
