WebAn arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k. Example: a1 = 25 a (n) = a (n-1) + 5 Hope this helps, - Convenient Colleague 1 comment ( 6 votes) Upvote Downvote Flag more Christian
