Copy last record to new record

Hello all,Hope I can get a little info from someone.
What I am trying to do is take the last row field end_odometer and have it auto populate the next row to start_odometer. What would be the best way of do that? Example below

id | start | end
1 | 1000 | 1500
2 | 1500 | 1567
3 | 1567 | 2001
4 | 2001 | 2523
And so on


Thanks A lot for any kind of help on this.
