Determine whether the sequence is arithmetic geometric or neither and explain 3, 3/2, 1, 3/4

the sequence is neither arithmetic nor geometric.

Step-by-step explanation:

3/2 - 3 = - 3/2

1 - 3/2 = - 1/2

since - 3/2≠-1/2 then this isn't an arithmetic sequence

(3/2) / 3 = 1/2

1 / (3/2) = 2/3

since 1/2≠2/3 then this isn't a geometric sequence

neither it is arithmetic nor geometric.
