If one was to sum a series by grouping each two terms would that be legtimate?
i.e if you have an alternating series than grouping two terms would not be would it? i.e 1,-1,1,-1... would sum to 0 if you grouped them or 1 depending on how you group it.
Sometimes the only way to write a series under a summation sign is to group two elements in the series together.
