Definition of sequence in geometric progression

Main post link -> https://brilliant.org/assessment/s/algebra-and-number-theory/663850/

In this week's "Clever 4-term Sequences" (from level 3 of Algebra and Number Theory), is the sequence (1,4,2,8) valid or all terms have to be in the order of the progression like (1,2,4,8) or (8,4,2,1)?

no only sequences which are arranged in order of geometric progression must be taken into account

(8,4,2,1) and (1,2,4,8) are distinct geometric progressions.
