 Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 60th year, we have over 367,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”). Other ways to Give

 OFFSET 1,2 COMMENTS a(n) = A063676(n+1) - A063676(n) (by definition) LINKS Table of n, a(n) for n=1..50. EXAMPLE The arithmetic mean of the first 7 A063676-elements is (1 + 2 + 4 + 7 + 11 + 16 + 24) / 7 = 65 / 7 which is not an integer; but skipping A063676(5) = 11 yields a(7) = 54 / 6 = 9.
