This is an excel question and you have the document online for the info, Time Series-Trend (version 2).xlsx by Juan ?? Anyway, it is a dataset from 1-134 with a growth rate of 1.6519 and an regression equation of y=1.6519x + 77.44. Uptrend and the average monthly growth rate in millions is 1,651,900. The question is asking "What is the average monthly growth rate - geometric mean - you have a beginning and ending value". I don't understand what this means or how to calculate this.
