1. Using the table below as your reference, can you easily predict the number of job gains in 2020 based on the years before? If yes, explain what method(s) you would use to predict the job gains in quarter 4 (Q4) for the year 2020. If no, explain what would make it difficult for you to predict job gains for Q4 in 2020.
