The president of State University wants to forecast student enrollment for this academic year based on the

Year Enrollments
5 years ago 15,000
4 years ago 16,000
3 years ago 18,000
2 years ago 20,000
Last year 21,000
What is the forecast for this year using exponential smoothing with trend if a = 0.5 and B = 0.3?
Assume the forecast for last year was 21,000 and the forecast for two years ago was 19,000, and that the trend estimate for last years forecast was 1,500.
