Hey,
I was away when we did this topic and my textbook doesnt explain it at all!
Could someone please explain the whole idea to me? Im so confused!!!
Here are a few questions from my book. What do all the numbers mean? How do you do such questions?
1)
5
Σ 3r^2
r=1
2)
7
Σ 5n-6
3
Any help would be much appreciated!
Thanks in advance!
