Answer:

Since #r_1 = r_2# the sequence is geometric.

Explanation:

In a geometric sequence, a constant common ratio #r# is maintained all through out the sequence.

The common ratio #r# is obtained by dividing a term by its preceding term.

The sequence is: #24, 12, 6#

1) # r_1 = 12/24 =1/2#

2) #r_2 = 6/12 = 1/2#

Since #r_1 = r_2# the sequence is geometric.
