Answer:
see the explanation
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
we have
![3, 8, 13, 18, 23,...](https://tex.z-dn.net/?f=3%2C%208%2C%2013%2C%2018%2C%2023%2C...)
Let
![a_1=3\\a_2=8\\a_3=13\\a_4=18\\a_5=23\\](https://tex.z-dn.net/?f=a_1%3D3%5C%5Ca_2%3D8%5C%5Ca_3%3D13%5C%5Ca_4%3D18%5C%5Ca_5%3D23%5C%5C)
------>![a_2=a_1+5](https://tex.z-dn.net/?f=a_2%3Da_1%2B5)
------>![a_3=a_2+5](https://tex.z-dn.net/?f=a_3%3Da_2%2B5)
------>![a_4=a_3+5](https://tex.z-dn.net/?f=a_4%3Da_3%2B5)
------>![a_5=a_4+5](https://tex.z-dn.net/?f=a_5%3Da_4%2B5)
so
the common difference between consecutive terms is equal to 5
we can rewrite the formula as
-----> given formula
For n > 1
where
an is the term that you want to find (position n)
a(n-1) is the known term position (n-1)
Find a_8
For n=8
![a_8=a_(_8_-_1_)+5](https://tex.z-dn.net/?f=a_8%3Da_%28_8_-_1_%29%2B5)
![a_8=a_7+5](https://tex.z-dn.net/?f=a_8%3Da_7%2B5)
I need to know a_7
or
we know that
The general formula for arithmetic sequence is equal to
where
an is the term that you want to find (position n)
a_1 is the first term
d is the common difference
n is the number of terms
we have
![a_1=3](https://tex.z-dn.net/?f=a_1%3D3)
![d=5](https://tex.z-dn.net/?f=d%3D5)
substitute
so
For n=8
