Description Usage Arguments Details Author(s) Examples

This uses item model 10 to create number series items - Combined identification of parallel sub-sequences and progressively evolving coefficients of change.

1	imTen(items, logic = "one", n = 2, arith = "add")

`items`	Generate a random mix of items.
`logic`	The combination of sequences follow two logic ("one" or "two").
`n`	The value that the arithmetic operator uses to calculate the next value
`arith`	The arithmetic operator of your choice ("add","substr","multi","div").

The number series items are a combination of Arithmetic, linear sequence and progressive coefficient.
First logic is combining sequences x y x y x y x y = one simple (cannot be controlled), one progressive .
Second logic is combining sequences x y x y x y x y = two progressive. The minimum number of items that will be generated is 2.
Logic analogous to the Item Model 5, but at least one sub-sequence involves a progressively evolving coefficient. Sub-sequences involve items from Item Families 1, 3, and 7. Example: The coefficient of change between odd elements in the sequence increases by 1. The coefficient of change between even elements increases by -1. (2 8 4 7 7 5 11 2 16 (-2) (22)).

When using the first logic, n corresponds to the change in the progressive pattern. However, the simple pattern is fixed and hence drawn randomly.
