 OFFSET 1,1 COMMENTS a(n) = A350617(n) + prime(n). Also a(n) = 2^A350883(n) * A350617(n+1). This is a compressed version of A350877: when A350877 reaches an even number e, the following steps repeatedly divide e by 2 until an odd number is reached. In the present sequence the results of those divisions are suppressed. For example, A350877 (n>=2) begins 1, 3, 6, [3,] 8, [4, 2, 1,] 8, [4, 2, 1,] 12, [6, 3,] 16, [8, 4, 2, 1,] 18, ..., where the suppressed terms are enclosed in square brackets. The scatterplot of the present sequence is the same as the red-colored portion of Sigrist's colored scatterplot in A350877. LINKS N. J. A.
