Ur getting scammed lol but if you are looking at a constant term of a flat amount added each year, then the answer would be 96/8 and that would equal 12 so 12 dollars a year.
But if you are looking for yearly increase percentage wise then, first we would put out an equation, 1296 = 1200(x)^8= you would then put it into a calculator because the eighth root is omega hard to calculate, but the end answer is
1.009667
