This uses item model 11 to create number series items - Identification of alternating coefficients of change.
Usage
imEleven(items = 1, fun1 = "add", fun2 = "add")
Arguments
items
Generate a random mix of items.
fun1
The argument decides the arithmetic to be employed for Neighbouring objects. There are only two arithmetic: add, substr.
fun2
The argument decides the arithmetic to be employed for the two values between the grouped objects. There are two arithmetic: add, substr.
Details
This function creates number series that is a combination of Neighbouring objects and 2-sequence coefficient. Multiplication and Division are removed since the calculated value is too big. Example: A sequence whose coefficient of change alternates between (add 6) and (multiply by 2). 1 7 14 20 40 46 (92) (98).
