:the table shows the number of trucks registered in a city each year. suppose the growth continues exponentially. how many trucks registered in the city in year 9? round to the nearest whole number. enter your answer in the box.

It seems its starts out increasing by 10 + 1. However each year it adds 1 more so for year three for example it would be 121 + 12 instead of 11 for the simple fact it increases +1 every year. So in conclusion for the rest of the trucks per year would increase by 10+ ? depending on which year. 

Year 3 +12 =133 
Year 4 +13 =146
Year 5 +14 =160
Year 6 +15 =175
Year 7 +16 =191
Year 8 +17 =208
Year 9 +18 =226

And so on. :)
