My solution, don't know why I don't have the exactly same results.

I agree with Bolide that the answer is not the best. Actually I would go farther and say that the given answer is wrong. The sales data has a time varying element that is consistent in both years, and is such that the first six weeks of each year is a valley with sales in the range of 50 to 126. To conclude that the following year will have sales of 200 to 330, just isn't supported by the historical data. Unfortunately I don't have access to the predictive tools yet, so can't suggest an alternate solution using those tools. However, even a simple average of the first six weeks' values would provide a more accurate solution than the one provided.

Having fun learning Alteryx and looking forward to learning about the predictive tools!

Thanks.

I can't believe I got this one. Well, maybe not the exact numbers, but close enough!

Solution attached! :-)

First time using Time Series tools - it was a good challenge to get more familiar with these tools.
