Final answer:
To predict Praiville's population for 2018 based on the exponential doubling pattern from 2014-2017, it is projected to be 32000 residents.
Step-by-step explanation:
Josh is looking to predict the number of residents in Praiville for the year 2018. Based on the given data that shows the population doubling every year from 2014 to 2017, we can recognize a pattern of exponential growth.
The population counts for the respective years are: 2000 for 2014, 4000 for 2015, 8000 for 2016, and 16000 for 2017. To predict the population for 2018, we would continue this trend of doubling. Therefore, the predicted population for Praiville in 2018 would be 32000 residents.
