Here's the questionI am having trouble understanding (b)(v), especially the terms forecast dynamically.How do I actually forecast? I tried using values in Equation [4] to estimate [3] as [4]+[3]= the next term, but is this correct?If that is the case, I have around 300+ observations of data, and with my method I will be facing a lot of problem with repetition works, but Macro or similar loop-programme command would solve it but I haven't got a clue.Anyone got any idea?

dynamically forecast means change the forecast with time.So doing as you said ([4]+[3]=next term) seems correct to me. If you have 300 observations and you're expected to forecast to the end and compare, then I would certainly suggest writing a small program to do this. Shouldn't be too time consuming.
