Complete the pattern: 486, 162, 54, 18, _, _

Answer 1

162 / 486 = 162 ∙ 1 / 162 ∙ 3 = 1 / 3

54 / 162 = 54 ∙ 1 / 54 ∙ 3 = 1 / 3

18 / 54 = 18 ∙ 1 / 18 ∙ 3 = 1 / 3

The ratio of any successive terms of the sequence is equal

Sequence is geometric progression with first term 486 and a common ratio 1 / 3

Next two terms are:

18 ∙ 1 / 3 = 6

6 ∙ 1 / 3 = 2
