<h3>Answer:</h3>

<h3>Explanation:</h3>
The
th term of an arithmetic sequence is explicitly defined as
where
is the first term of the sequence and
is the the common difference.
From the given first five terms of the sequence we can see that the first term is
so
.
The common difference,
, can be calculated by
so we'll find the common difference of the given sequence by letting 
.
Now let's plug everything we know.



Answer:
7^2 =49
Step-by-step explanation:
Exponents represent a number and how many times you multiply it by itself. So 5^2 is 5*5 or 4^3 is 4*4*4. So 7^2 is 7*7, which is 49!
x = 95°
the polygon has 5 sides so you do n - 2 which is (number of sides - 2) this gives us 3. now multiply 3 times 180, this gives us 540. now add up all the sides that you know, 104, 117, 100, 124, this is 445 now subract 445 from 540 and that is what gives us 95°
73 that will be hope this is right ok byeeee
