Answer:
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
