Answer:
Step-by-step explanation:
we know that
In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, called the common difference
The formula for an Arithmetic Sequence is equal to
where
d is the common difference
n is the number of terms
a_1 is the first term of the sequence
In this problem we have
substitute
so
<u><em>Find the first ten terms</em></u>
For n=2 ---->
For n=3 ---->
For n=4 ---->
For n=5 ---->
For n=6 ---->
For n=7 ---->
For n=8 ---->
For n=9 ---->
For n=10 ---->
The sequence is
