## anonymous one year ago What is the sum of the first n terms of this series? 4 + 6 + 8 + 10 + 12 + ⋯

1. anonymous

2. DanJS

notice when i=1 the term is 4, that will eliminate a couple answers off the bat

3. DanJS

They are asking for a sum up to nth term... $\sum_{1}^{n}$

4. anonymous

so if it doesn't equal 4 then I should eliminate that answer?

5. DanJS

Right, let i=1 and calculate the ( ) Quantity...

6. DanJS

Notice that each term increases by 2, that helps choose... ( something +2 ) maybe

7. anonymous

C?

8. DanJS

yes, the third one, but i sorta gave you the answer with those two infos, sorry

9. anonymous

since it's n instead of the infinity symbol and it's 2+2

10. DanJS

right, they want n terms, not the infinite sum

11. anonymous

I'm slow enough that I don't realize those things, lol. Thank you for your assistance!! xoxo.
