neither
1. 2, 4, 6, 12, 24,...

2. 2/3, 4/3, 6/3, 8/3

3. 24,12, 6, 3/2 ...

Answer 1

1) Arithmetic progression

2)It's a geometric progression

3) Also geometric.

Arithmetic progressions have fixed difference between them

Answer 2

1. The sequence is geometric since it is being multiplied by 2.
2. The sequence is geometric since it is being added by 2/3.
3. The sequence is geometric since it is being multiplied by 1/2.
