Yeah, I believe you are correct!
Answer:
Step-by-step explanation:
we know that
The rule to calculate the a_n term in an arithmetic sequence is
where
d is the common difference
a_1 is the first term
n is the number of terms
we have

Remember that In an Arithmetic Sequence the difference between one term and the next is a constant. and this constant is called the common difference
so


Find the 96th term of the arithmetic sequence
we have

substitute
7r=-7/2
divide both sides by 7 to get r by itself
(7r)/(7) = (-7/2)/(7)
if you don't quite see it, think of multiplying both sides by 1/7 instead (its the same thing as dividing by 7)
(7r)*(1/7)=(-7/2)*(1/7)
r=-1/2
