GDP was a linear function of time (year) during the period of 1985-99. The slope is positive. Equation is: GDP(y)=(y-1985)*0.032*577+577=577*[(y-1985)*0.032+1] check: if y=1985, then GDP=577 . So, we need to solve for "y" this equation: GDP=4000=577*[(y-1985)*0.032+1]then, y=[4000/577-1]/0.032+1985 =  2170.4  we solveGDP=2200=577*[(y-1985)*0.032+1]  [4 is replaced by 2.2] y=[2200/577-1]/0.032+1985=2072.9  [almost 2073]
