Answer:
The expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
Step-by-step explanation:
Given the sequence
9, 17, 25, 33
a₁ = 9
<em>Determining the common difference</em>
d = 17-9 = 8
d = 25-17 = 8
d = 33-25 = 8
As the common difference between the adjacent terms is same and equal to
d = 8
Therefore, the given sequence is an Arithmetic sequence.
An arithmetic sequence has a constant difference 'd' and is defined by
substituting a₁ = 9, d = 8 in the equation
Therefore, the expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
u take ur known variables and fill them in, pi will be filled in as 3.14
Example:
Then divide both sides by 3.14, after that it should be (number) =r². since it's squared you have to find to square root of both.
Example:
therefore in this example the radius is 7
