 OFFSET 2,1 COMMENTS Next term is > 5000000. - Larry Reeves (larryr(AT)acm.org), Jan 03 2003 There are no more terms. If the sum of five consecutive composite numbers is not divisible by 2 or 5 then it is 7 or 23 modulo 30. The sum of six consecutive composite numbers cannot be 7 or 23 modulo 30. - Jens Kruse Andersen, May 11 2014 LINKS Table of n, a(n) for n=2..5.
