Mt. Bear is a ski resort in California. Many guests visit there; however, most of them come in the winter season because of the phenomenal skiing. A group of hotels has analyzed their demand for the last three years (see the table below).

Year	Quarter	Demand
2019	1	18,000
	2	14,900
	3	13,700
	4	19,100
2020	1	20,700
	2	17,000
	3	16,500
	4	19,100
2021	1	20,700
	2	12,100
	3	13,200
	4	22,400

Using a smoothing parameter of 0.2 and an initial forecast of 17,500, forecast demand for the four quarters in 2022. can you please show steps because this is super confusing to me.
