Answer:((-1)^n)(3n).

I'm not really sure about this answer but here you go.

Step-by-step explanation:This sequence has common ratio (-1) and first term is -1 (so called geometric sequence). General formula is nth term is (-1) × ((-1)^(n-1))=(-1)^n. Multiplying general term of both the sequences, we get general term is ((-1)^n)(3n).

Maybe the answer is right!
