How to determine the sum of the series?
The series is given as:
6 8 10 12 14 16 18 20 22 24 26
The above series is an arithmetic series with the following parameters:
First term, a = 6
Last term, L = 26
Number of terms, n = 11
The sum of the series is calculated using:
[tex]S_n= \frac{n}{2} *(a + L)[/tex]
This gives
[tex]S_n= \frac{11}{2} *(6 + 26)[/tex]
Evaluate
[tex]S_{11} = 176[/tex]
