Which of the following represents the sum of the series? 6 8 10 12 14 16 18 20 22 24 26
stira [4]

The sum of the arithmetic series 6 8 10 12 14 16 18 20 22 24 26 is 176

<h3>How to determine the sum of the series?</h3>

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:

S_n= \frac{n}{2} *(a + L)

This gives

S_n= \frac{11}{2} *(6 + 26)

Evaluate

S_{11} = 176

Hence, the sum of the arithmetic series 6 8 10 12 14 16 18 20 22 24 26 is 176
