Hi, i'm actually a good student i do my own work but this stuff makes no sense to me, my teacher isn't the best so if you could provide a answer and if possible a explanation for each problem on how you got it, it would be great. also kind of needed asap. you. 1. enter the explicit rule for the geometric sequence 15,3,3/5,3/ an= _ 2. enter a recursive rule for the geometric sequence 10,-80,640,- a1=_; an=_ 3. the reursive rule for the a geometric sequence is given a1= 2; an= 1/3 an-1 enter the explicit rule for the sequence an=_ 4. the explicit rule for the sequence is given an= 1/2(4/3)n-1 enter the recursive rule for the geometric sequence a1=_; an=_
