Say the first point of v1 was 1 (+/-.5)
and the first point of v2 was 3(+/-2)

Well, it seems to me that the sum vector would be

(.5 + 1) = 1.5 Low side
(1.5 + 5) = 6.5 High side
Summed is 8  - ave is 4 
therefore answer is 4(+/-2.5)

Hmm that is sum of both vector elements AND deviation. I think we can 
easily prove this is always so.

Am I right?
