This site is supported by donations to The OEIS Foundation.

 Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing. Other ways to donate

 Hints (Greetings from The On-Line Encyclopedia of Integer Sequences!)
 A115839 Self-describing sequence. The n-th integer of the sequence indicates how many integers of the sequence are strictly < 5n. 0

 OFFSET 1,2 COMMENTS Terms computed by Gilles Sadowski. In building step by step the sequence one has sometimes the choice for an integer. If so take the smallest available one. LINKS EXAMPLE A(7)=15 because there are 15 integers in the sequence which are strictly < 35 (they are 1,5,6,7,8,10,15,20,25,26,30,31,32,33,34) CROSSREFS Sequence in context: A202014 A319266 A263093 * A200259 A262513 A130206 Adjacent sequences:  A115836 A115837 A115838 * A115840 A115841 A115842 KEYWORD base,easy,nonn AUTHOR Eric Angelini, Feb 01 2006 STATUS approved
