Question 1 options:

4, 10, 16, 22, ...

4, 4, 4, 4, ...

9, 4, - 1, - 7, ...

2, - 6, 18, - 54, ...

1.

geometric sequence

2.

arithmetic sequence

3.

neither

4.

both

4,10,16,22, ... is an arithmetic sequence

4,4,4,4, ... is a geometrical sequence

9,4,-1,-7, ... is an arithmetic sequence

2,-6,18,-54, ... is a geometrical sequence

Step-by-step explanation:

4,10,16,22, ... Is an arithmetic sequence since 10-4=6 and 16-10=6

4,4,4,4, ... is a geometrical sequence because 4/4=1

9,4,-1,-7, ... is an arithmetic sequence since common difference is 4-9=-5 and - 1-4=-5

2,-6,18,-54, ... is a geometrical sequence because - 6/2=-3 and 18/-6=-3
