Question

Look at the following sequence.

Answer 1

Answer:

geometric sequence

Step-by-step explanation:

If the sequence is geometric then there is a common ratio r between consecutive terms.

$\frac{a_{2} }{a_{1} }$ = $\frac{36}{54}$ = $\frac{2}{3}$

$\frac{a_{3} }{a_{2} }$ = $\frac{24}{36}$ = $\frac{2}{3}$

$\frac{a_{4} }{a_{3} }$ = $\frac{16}{24}$ = $\frac{2}{3}$

Then sequence is geometric with common ratio r = $\frac{2}{3}$ ( ≈ 0.67 )
