this one's similar to the other question you had simplify the sigma to something that's easier to apply the sumation formulas. so 1st simplify it to ∑4i/n^2. you want to get ∑i in the end, so take out the 4/n^2 and put that in front of the ∑ to get (4/n^2)∑i. the formula for ∑i was (n^2+n)/2 so from there on, you can do simple algebra to get the answer :)
