how to derive a formula to find the sum of a sequence?
Posted:

So, let's say I have a question like 5 SUM (k+1) k=1
5 being the upper limit k being lower limit k+1 being the sequence
How would I find a formula to get the answer, without actually adding every k+1 ect
The teacher told us to do something like this for the first step: 1 2 3 4 5 5 4 3 2 1 sum of the top and bottom = 6.. From there I'm lost
Can anyone help?
Thanks
