$\begingroup$ OEIS has this sequence. $\endgroup$– greenturtle3141Commented Mar 8, 2017 at 19:53

$\begingroup$ @BeastlyGerbil In what way did my original question differ from your model question. $\endgroup$– GwenKillerbyCommented Mar 8, 2017 at 20:27

4$\begingroup$ @GwenKillerby Pretty much any bare OEIS sequence is a bad puzzle; such puzzles are uninteresting and, in many cases, are less an exercise in "deduce the pattern" and more one of "guess what sequence the poser was thinking of". Beastly Gerbil already pointed you at the post which mentions why these tend to make bad puzzles; maybe you should read it instead of challenging the helpful critique. $\endgroup$– Rubio ♦Commented Mar 8, 2017 at 21:00
