On the k-th step (k=1,2,3,...) move a distance of k in the direction of zero. If the number landed on has been landed on before, move a distance of k away. %e A324691 Starting at 2, the points visited are 2,1,-1,-4,0 and the only move away from zero, from -1 to -4, occurs at a negative position. Thus 2 is a term. %Y A324691 Cf. A228474, A324660-A324692. %K A324691 nonn %O A324691 0,1 %A A324691 _David Nacin_, Mar 11 2019
