Answer:
Arithmetic sequence.
Step-by-step explanation:
We have been given 9,5,1 and -3
We need to check what kind of sequence is this.
[tex]d=a_2-a_1[/tex]
d is common difference we will check difference of consecutive terms.
[tex]5-9=-4[/tex]
[tex]1-5=-4[/tex]
[tex]-3-1=-4[/tex]
We can see the difference between all the terms are same that is -4
So, this is an arithmetic sequence.
Arithmetic sequence is the sequence in which the difference between consecutive terms are same.
