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
