Question

the first three terms of a geometric sequence are as follows.
162, 54, 18
find the next two terms of this sequence.
162, 54, 18, \square, \square

Explanation:

Step1: Find common ratio $r$

$r = \frac{54}{162} = \frac{1}{3}$

Step2: Calculate 4th term

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

Step3: Calculate 5th term

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

Answer:

6, 2
