The number of anti-government militia groups was 512 in 2009, and it increased by approximately 299 groups per year for the period 2009€“2014.
a. Complete Table 32 to help find an expression that stands for the number of militia groups at t years since 2009. For example, t = 2 stands for the year 2011, because 2011 is 2 years after 2009. Show the arithmetic to help you see a pattern.

b. Evaluate the expression you found in part (a) for t = 5. What does your result mean in this situation?
