Hi Abhishek,

try with below code and modify the field api names as per your org. 
trigger ContactsCreation on Account (after insert) {
    
    List<Contact> conlist = new List<contact>();
    
    for(account acc:trigger.new){
        
        if(acc.Number_of_Locations__c !=Null){
            
            for(integer i=1;i<=acc.Number_of_Locations__c;i++){
                
                contact con = new contact();
                con.LastName = acc.Name+i;
                con.phone = acc.phone;
                con.AccountId = acc.id;
                conlist.add(con);
            }
            
        }
    }

try with below code and modify the field api names as per your org.
  
trigger ContactsCreation on Account (after insert) {
    
     decimal number=0;
    for(account acc:trigger.new){
       if(acc.Number_of_Locations__c !=Null){
       number=acc.Number_of_Locations__c;
          }
       }
      List<Contact> conlist = new List<contact>();
          for(integer i=1;i<=number;i++){
                
                contact con = new contact();
                con.LastName = acc.Name+i;
                con.phone = acc.phone;
