For a slightly different (but less general, perhaps) version, there's also: (map (fn [[a b]] (+ a b)) (partition 2 (range 1 7))) By the way, don't get caught out by this: user=> (partition 2 (range 1 7)) ((1 2) (3 4) (5 6)) user=> (partition 2 (range 1 8)) ((1 2) (3 4) (5 6)) user=> (partition 2 (range 1 9)) ((1 2) (3 4) (5 6) (7 8)) -- Michael Wood <esiot...@gmail.com> -- You received this message because you are subscribed to the Google Groups "Clojure" group.
