# imSeven: Item Model 7 In numGen: Number Series Generator

## Description

This uses item model 7 to create number series items - Identification of complex coefficients of change

## Usage

 ```1 2``` ```imSeven(vOne = 1, vTwo = 3, items, seed = 1, logic = "one", random = FALSE) ```

## Arguments

 `vOne` The first value in the complex coefficient (x). Can be a sequence of values or a specific value. `vTwo` The second value in the complex coefficient (y). Can be a sequence of values or a specific value. `items` Generate a random mix of items. `seed` To get the same random sampling of items `logic` "one" or "two" `random` If random=FALSE, the items will follow in sequential order.

## Details

This function creates number series that is a combination of Arithmetic, Linear and Complex coefficient. Ability to identify complex coefficients; the coefficient of change involves a combination of arithmetic operations (e.g. addition and multiplication) applied serially.
There are two logic to calculate the number series. First logic of complex coefficient = i*x+y.
Second logic of complex coefficient = (i+x)*y.
. Example: Each element in the sequence is derived from the preceding by adding two and multiplying the result by two. (2 8 20 44 92 (188)).

## Examples

 ```1 2 3 4 5 6``` ```#Draws 5 items randomly. imSeven(vOne=1,vTwo=3,items=5,seed=2,logic="one",random=TRUE) # Calculates all combinations # Items and seed arg is ignored. imSeven(vOne=1:2,vTwo=1:3,items=5,seed=2,logic="one",random=FALSE) ```
