Double exponential smoothing please help, thanks

Park visitors the first 6 months of the year: 133, 183, 285, 640, 1876, 2550 (January through June)

(a) Using a = 0.15, b = 0.10, apply DES to estimate July and August numbers. (Use the first two data points to get the method started.)

(b) The number of visitors for July and August are: 2150 and 2660. Continue to update the DES process to this point and then estimate the September and January (next year) numbers.

(c) Does the January estimate make sense to you based on last years January observation? If not, what could be wrong with the approach?
