 OFFSET 1,1 COMMENTS Conjectures: (1) Sequence is infinite. (2) For every n there are infinitely many arithmetic progressions with n successive primes. A088252(n)=n*A088250(n)+1=n*A088251(n)-n+1. - Farideh Firoozbakht, Feb 21 2004 LINKS EXAMPLE 2 2 3 3 5 7 331 661 991 1321 ... CROSSREFS Cf. A002110, A088250, A088251.
