Determine whether this sequence is arithmetic or geometric. Find the next three terms.
4. 3, 12, 21, 30, ....
A.40, 50, 60
B.38, 46, 54
C.39, 48, 57
D.36, 32, 39
A?
Thank you
A is not the correct answer here unfortunately.
Also, are the "Arithmetic" or "Geometric" parts of the answers missing? They were there for the previous questions I helped you with.
Yea but on my paper it doesn't say it like it does on the previous questions so I kind of got confused.
The answer is C.
Alright, yeah. That's kind of confusing. Still, A is not the correct answer.
A's next 3 terms assume this is an arithmetic sequence, as the common difference is +10. (60-10=50 & 50-10=40). That is not the correct sequence based on the first 4 terms of 3, 12, 21, and 30.
