Which of the following represents the sum of the series? 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26

 The correct option is

(A)

Step-by-step explanation:  We are given to select the correct summation form that represents the sum of the following series :

6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26.

We see that

the first term of the series, a = 6.

And, there is a common difference in any two consecutive terms given by

d = 8 - 6 = 10 - 8 =  .  .  .  = 2.

This implies that the given series is arithmetic with first term a = 6 and common difference d = 2.

We know that

the sum of first n terms of an arithmetic series with first term a and common difference d is given by

Since there are 11 terms in the given series, so the required sum is given by

Thus, (A) is the correct option.

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
