I am currently taking Advanced Algebra and we have a test with a couple of questions about Shifted Geometric Sequences. I understand how to find a specific term in a sequence (The 10th term, etc.) when I am given an equation such as Un=Un1(1+0.6)+30 with the first term, and I can identify a shifted geometric sequence with no issues. However, my problem is finding the equation when I am given the terms. Example?: 0, 20, 38, 44, 68 Help?? Last edited by Imnomermaid112; October 3rd, 2016 at 02:05 PM.

Are you sure the 4th term is 44 and not 54? Last edited by skipjack; October 6th, 2016 at 05:56 AM.

Yes, that's what I meant, thank you for pointing out my error. Anyways, I figured out how to do it, so I won't need any further assistance. Thank you!

I just asked about the 44 term to try and make some mathematical sense from the sequence the OP listed.
