How about (map - seq1 seq2) ?
An example or two of the desired output would be helpful.

Christophe's solution seems to work.
basically I just wanted to remove
(4 6 8 10) from
(2 3 4 5 6 7 8 9 10)
so I end up with
(2 3 5 7 9)

If what you really want to do is treat those sequences as sets, then
you can use clojure.seq/difference:
1:1 user= (def seq1 (list 2 3 4 5 6 7 8 9 10))
#'user/seq1
1:2 user= (def seq2 (list 4 6 8 10))
#'user/seq2
1:3 user= (require 'clojure.set)
nil
1:4 user= (clojure.set/difference (set seq1)
ah, that works too! thanks!

If I have two sequences as follow:
(2 3 4 5 6 7 8 9 10)
(4 6 8 10)
what's the best way to subtract the 2nd sequence from the first one?
The best I can come up with was to do (first) on 2nd sequence and
Thank you for such a detail email on the algorithm. I'll certainly keep
that in mind.
This is so far been the most impressive thing I've found about clojure.
the community is very friendly and helpful. You've made a newbie
feel much more comfortable.

Is the order of the second sequence important? If not:
(defn subtract [a b]
(remove (into #{}
