Given that X = 0 represents 20X0 quarter 1 what are the forecast sales levels for 20X5 quarter 4? – this is a regression lines and time series question…i need help with finding X at 20X5 quarter 4 please

They say that X=0 for 20X0 quarter 1,so X=1 for 20X0 quarter 2,X=2 for 20X0 quarter 3,X=3 for 20X0 quarter 4 and so on,then for 20X1 quarter 4,X=7,for 20X2 quarter 4,X=11,for 20X3 quarter 4,X=15,for 20X4 quarter 4,X=19,for 20X5 quarter 4,X=23
okay you lost me a bit…. how does X=7 in 20X1 quarter 4?….. is it that 20X1 quarter 1 begins with X being equal to 4 and then, 5 , 6 ,7, then 20X2 quarter 1 also begins with X=7 , then 8,9,10?…..a quarter is 4 parts obviously…..but i’m confused how you get your numbering
