I think it is C but im not too sure, wait for another answer that has more facts behind it.
Can you add the whole question I think it may be 6/4
Answer:
Step-by-step explanation:
find the value of t
Arithmetic sequences have a common difference between consecutive terms.
Geometric sequences have a common ratio between consecutive terms.
Let's compute the differences and ratios between consecutive terms:
Differences:

Ratios:

So, as you can see, the differences between consecutive terms are constant, whereas ratios vary.
So, this is an arithmetic sequence.
