- abhishekjha 9y ago0 < i <= n or upto n-1 respectively.
- vlasev 9y agoSometimes we even leave it as "i" instead of "0 < i < n" or "i = 1 to n". Sometimes the range of the summation doesn't even need to be determined in intermediate steps.
- EvilTerran 9y agoThere's also this formulation, which I'm quite partial to: --- \ / --- i∈[1,n]
