Accepted Solution

A:

What is the explicit rule for this geometric sequence?

29,23,2,6,...

For n=0 we have

an=29⋅3n=0≠29

an=3(29)n−1= -1≠29

an=3(29)n=0≠29

an=29⋅3n−1=-1≠29

And

For n=1 we have

an=29⋅3n=78≠29

an=3(29)n−1=77≠29

an=3(29)n=78≠29

an=29⋅3n−1=-77≠29

All four formulas are non-correct
