I thank all of you again for helping me, and having the patience to withstand my idiocy. I understand the concept, but maybe it's the wording of the question that is throwing me off, so I am wondering again if any of you could help me out with another question. Thank you all!!

Directions: Write the first five terms of the geometric sequence. Find the common ratio and write the nth term of the sequence as a function of n.

a1=64, a^k+1 =1/2a^k

Edit: Okay I looked at the question, and with the help of my sister, I figured it out. So I guess I can leave the question up just in case anyone is interested in doing it, however I stress again that it is very kind of all of you who have been able to help me. Also I'll leave this thread up in case I have questions with some of the other problems, or for others who are struggling as well in this portion of Precalculus. Thanks!
