See A191612 for the definition of the transformation which maps A005117 to this sequence here.
Conjecture: a(n) is also a "totally formed" sequence.

Examples

			a(10) = 14 because 14 is the only integer larger than 13 = A005117(9) and smaller than or equal to A005117(10) = 14 and simultaneously a multiple of the difference A005117(10) - A005117(9) = 1.
