algebra 2 question

OpenStudy (anonymous):

Evaluate the series: \[\sum_{(n-1)}^{4} (n+4)\]

OpenStudy (anonymous):

@agent0smith this is my last one for today :)

OpenStudy (mertsj):

Is that supposed to be n = 1 to 4?

OpenStudy (anonymous):

OpenStudy (mertsj):

So replace n with 5, 6, 7, and 8 and add them all up

OpenStudy (anonymous):

wait what?

OpenStudy (mertsj):

Do you know what replace means?

OpenStudy (anonymous):

yes, but why would putting those numbers in give me the answer?

OpenStudy (mertsj):

Because you problem says to find the sum of all the numbers you get by adding up all the n+4 values when n = 1, 2, 3 and 4 |dw:1391717430248:dw|
