how to reset identity column sequentially after deleting any row .

Question

I have a table like shown below

Id	Name
1	Aarti
2	Kriti
3	Priya

 if Kriti (2) got deleted then all her reputation earned is given to Priya (3) and all the rows below are promoted that is the table now  becomes like

Id	Name
1	Aarti
2	Priya
3	Rashmi
4	Nancy
