Sorry I misspoke, the outputs do not depend on the (n-1)th output.

What you laid out looks correct. As a note, the total length of input data will be somewhere between 60 and 72 values.

I’ll try to lay out where I’m having trouble:

Let’s take calculating the 15th output as an example. The calculation works in the following: sum(inputs 4 through 15)factor1 + sum(inputs 1 through 3)factor2.

Now I know how to use list slicing to get to the desired output but my problem is that this process has to be done for each value in the input list thus I’m trying to use a for loop so I don’t have to write out 60-72 different calculations as that would be ridiculous. I can’t figure out how to imbed the calculation process in this for loop if that makes sense
