 OFFSET 1,2 COMMENTS There are only 78 terms of A119754 known and s(78) is 0.58817497337288808165551740612048298329310794973566 to 50 decimal places. What is sum(1/A119754(k),k=1..infinity)? LINKS FORMULA a(2n-1) = numerator(s(n)), a(2n)=denominator(s(n)), where s(n)=sum(1/A119754(k),k=1..n). EXAMPLE a(5)=327, a(6)=935 since s(3)=1/5+1/11+1/17=327/935. CROSSREFS Cf. A119752, A119754. Sequence in context: A098912 A299685 A268225 * A301280 A153366 A057553 Adjacent sequences:  A120340 A120341 A120342 * A120344 A120345 A120346 KEYWORD nonn AUTHOR Walter Kehowski, Jun 23 2006 EXTENSIONS This is not really a sequence. The standard OEIS convention would be to split this into two cross-referenced sequences with keyword "frac". - N. J. A. Sloane, Jul 22 2006 STATUS approved
