Plug in the values of 2 thru 10 for n and add them together

OpenStudy (anonymous):

-7 = 2, -9 = 3, etc

OpenStudy (anonymous):

I don't understand that

OpenStudy (anonymous):

The equation is -2n -3. \[\sum_{10}^{2}\]

@DanJS

OpenStudy (anonymous):

Aeeee bruh try to help her wit her first one to please

OpenStudy (anonymous):

i gave u a medal also

OpenStudy (anonymous):

\[\sum_{n=2}^{10}\] This tells you to use the values of 2 thru 10 in the equation -2n-3. Then add the sums together. The first would be (-2 x (2)) - 3 which equals -7...the secind would be (-2 x (3)) -3 which equals -9...do the same for 4,5,6,7,8,9,10..

OpenStudy (anonymous):

I still don't understand because I don't know how to solve these and I have to be don't before 2:30 and I still have 2 more to do and they consist of the same thing

OpenStudy (anonymous):

You have an equation -2n -3 correct?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

So if n=2 what does the equation equal?

OpenStudy (anonymous):

-7?

OpenStudy (anonymous):

Correct and for 3 it would be? And for 4 it will be what? etc all the way to n=10.
