In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, and this constant is called the common difference
we have
Let
we have that
so
The common difference is equal to 9
We can write an Arithmetic Sequence as a rule:
where
a_n is the nth term
a_1 is the first term
d is the common difference
n is the number of terms
Find the 38th term of the arithmetic sequence
we have

Answer:
The Dimension of new garden is
Step-by-step explanation:
Given:
Perimeter of new garden = 70 feet.
Let the length of the new garden be 'l'.
Also Let the width of the new garden be 'w'.
We need to find the dimension of new garden.
Now Given:
Length is 5 feet shorter than three times it width.
framing the equation we get;
Now we know that;
Perimeter of rectangle is equal to twice the sum of length and width.
framing in equation form we get;
Now Diving both side by 2 using Division property of equality we get;
Now Substituting equation 1 in above equation we get;
Adding both side by 5 Using Addition Property of equality we get'
Now Diving both side by 4 using Division property of equality we get;
Now Substituting the value of 'w' in equation 1 we get;
Hence The Dimension of new garden is
