I'm having trouble with this question:
Find the sum of arithmetic series 200 terms, k=1 and on the right of sigma it is 3k+4.
So it's something like: above sigma: 200, below sigma k=1 and on the right (3k+4).
I would edit this post if I could find a way to input those nice graphics with actual math symbols but I don't know where to find it on this site, so I hope it is clear.
Here are my answers:
term 1 is 3*1 + 4 = 7
term 2 is 3*2+4 = 10
term 3 is 13...
The sum of arithmetic series gives me this:
200/2 * [2x7 + (199)3]
= 6110
Please help.
