Details
This function creates number series creates a combination of sequences and ratios. TLogic analogous to the Item Model 13, but the second sequence belongs to the Item Model 9. As a result, pairs of elements following certain rule are embedded into a progressive sequence. Example: Sequence with coefficient of (+ 1) is interposed with pairs of elements which differ by 3. 1 5 8 2 209 212 3 41 (44) (4). Only the addition and substraction arimethic operators are used to generate the number series items.
