13 dollars per gallon
130\10 = 13
I'm guessing the repeating part is 89 at the end, so that

Then





###
An arguably quicker way without using geometric series:




Which equation have no solution ? Select all that apply
Answer:
Explicit form: 
Recursive form:
with
.
Step-by-step explanation:
The first term is 3 and we are dividing by 3 each time.
Another way to say we are dividing by 3 each time is to say we are multiplying by factors of 1/3.
If the first term is
and
is the common ratio then the geometric sequence in explicit form is:


The recursive form for a geometric sequence is
with
where
is the common ratio and
is the first term.
So the recursive form for our sequence is
with
.
