Step-by-step explanation:
Given:
- Series 5+11+17+...+251
To find:
- Summation notation of the given series
Summation Notation:
Where n is the number of terms and is general term.
First, determine what kind of series it is, there are two main series that everyone should know:
- Arithmetic Series
A series that has common difference.
- Geometric Series
A series that has common ratio.
If you notice and keep subtracting the next term with previous term:
- 11-5 = 6
- 17-11 = 6
Two common difference, we can in fact say that the series is arithmetic one. Since we know the type of series, we have to find the number of terms.
Now that brings us to arithmetic sequence, we know that first term is 5 and last term is 251, we’ll be finding both general term and number of term using arithmetic sequence:
<u>Arithmetic Sequence</u>
Where is the nth term,
is the first term and
is the common difference:
So for our general term:
And for number of terms, substitute = 251 and solve for n:
Now we can convert the series to summation notation as given the formula above, substitute as we get:
Answer:
degree 5
Step-by-step explanation:
the degree of a polynomial is determined by the term with the largest exponent and is the value of the exponent.
is the term with the largest exponent of 5
degree of polynomial is 5
