find a sum using sigma notation- MATH HELP
    #160569 - 12/11/08 02:23 PM (7 years, 11 months ago)

alright, I need some math help if there is anyone out there willing to throw me a bone here

30
E (5k+3)
k=1

The "E" is the Sigma sign. I need to find the sum of terms 1-30.

I know the long method but I know there is a short way to solve this problem, any help is greatly appreciated

the right equations you need should all be in your book. find out if its geometric or arithmetic, I guess right? then plug into the correct equation for sum of terms. :shrug:

its arithmetic (diff of +5)...eq's for arithmetic sequences:

eq. to find whatever term

"where a1 is the first term of the sequence,
d is the common difference, n is the number of the term to find."


eq for sum of certain number of terms

"where Sn is the sum of n terms (nth partial sum),
a1 is the first term,  an is the nth term."

Thanks!
