The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

 Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS"). Other ways to donate

 OFFSET 1,1 COMMENTS It is not known if there are other terms. There are no more terms < 10^10. REFERENCES R. K. Guy, Unsolved Problems in Number Theory, section B8. LINKS Paul Erdos, Some Unconventional Problems in Number Theory, Mathematics Magazine, Vol. 52, No. 2, Mar., 1979, pp. 67-70. See Problem 4. p. 68. EXAMPLE The largest value of m+d(m) for m < n=8 is 6+d(6)=10 = n+2, so 8 is in the sequence.
