Below Code Is Working For Insert Operation, Now I Need Max Number In the Case of Delete Operation How Can Get?


trigger SkillGroup_With_High_Rank on Skill_Group__c (after insert,before delete) {
        List<Id> AccnId = New List<Id>();
    public String Maxno;
   
    for(Skill_Group__c sk:Trigger.New){
        
        AccnId.add(sk.Account_Name__c); 
        system.debug('Accountssss'+AccnId);
    }
    list<aggregateResult> aggResults = [Select Max(Rank__c)RA from Skill_Group__c Where Account_Name__c In:AccnId ];
    
      system.debug('@@@@@@'+aggResults[0].get('RA'));
   Maxno = string.valueOf(aggResults[0].get('RA'));
    system.debug('$$$$$$$'+Maxno);
    for(Account ac: [Select id,Skill__c from Account where id In:AccnId]){
        ac.Skill__c = Maxno; 
    }

I have a process builder that is creating detail records and populating a few fields on creation. I also have an after insert trigger that is firing based on one of the fields that is populated during the record creation in the process builder.  Both function perfectly independently but when a record is created through the process builder that should fire the trigger it does not.  Any ideas or resources would be greatly appreciated since I'm new to triggers?
