How Can I verify data how many system bugs aging in particular client

[rmaheshwari@catex.com]

Hello 

Need to verify data 

Like created bugs = for ( Jan week 5 01/25/21-01/31/21 ) =6 count
Like closed bugs = for (Jan week 5 01/25/21-01/31/21 ) = 2 count

deficient from previous week =19

So calculation should be  = deficient from previous week +created bugs -close bugs

                                         = 19+6-2 =20
