How to auto increment Object Name when created or deleted

Hello All,
Need some help creating a process for creating an object name.  So the name will be a text value plus an auto incremetnted value.
For example Opportunity created would be 'Test_001 '
But what if the count is up to Test_089 and they need to delete 5 opportunities and the opportunities are in different sequences?  So they need to delete Test_055 and Test_041 and Test_020.  The naming needs to stay in sequencial order.  Is this possible?
How do I handle the naming when they do a data load?   
Thanks,
P

Create an auto number field. No need to display on screen. Create a workflow rule or process builder and set name as Test_ plus value of auto number field.

Thank you both for the replies.  RituSharma, will your approach work if a user deletes opportunity records?  Thank you.

Let's say you have 4 opportiunities with auto number as 01, 02, 03 and 04. Now you have deleted 02 and then you create a new one. So the auto number field of the new one will have 05. 02 is gone now and SF will not give this auto number to any opportunity.
