 OFFSET 1,1 COMMENTS All the terms in the sequence, except for a(2), are even. - K. D. Bajpai, Aug 26 2014 REFERENCES Archimedeans Problems Drive, Eureka, 26 (1963), 12. LINKS K. D. Bajpai, Table of n, a(n) for n = 1..10000 FORMULA Essentially same as A001043. EXAMPLE From K. D. Bajpai, Aug 26 2014: (Start) a(6) = 24 is in the sequence because prime(5) + prime(6) = 11 + 13 = 24. a(8) = 36 is in the sequence because prime(7) + prime(8) = 17 + 19 = 36.
