Using rolling last 3 months average for forecast into future months

Hi all 


I am trying to use my last 3 months average to get a forecast for the future. 


For example

month $

Jan 22 =1000

feb 22 =1200

mar 22 =900

aug 22 =200

sept 22 =500

oct 22 =900

Nov 22= 1100

Dec22 = Not know yet. I would need forecast to be the average of sep 22 to nov 22, say (500 + 900 + 1100) /3


Jan 23 = Average of Oct 22 - Dec 22

Feb 23 = Average of Nov 22 - Jan 23



Dec 23 = Average of Sep 23 - Nov 23


Is there any dax formulas which I can apply to achieve this ? Thank you so much!
