Using indexOf is an enormous waste of resources. The right way is initializing a variable with index's value, like this:

   Num. 
  {{i + 1}}

UPDATE:

If you are using pagination the index can be calculated this way:

   Num. 
  
  {{this.paginator.pageIndex == 0 ? i + 1 : 1 + i + this.paginator.pageIndex * this.paginator.pageSize}}
