Syntax to add one value to numeric field

[ReneeGerasimtchouk]

I have an incremental numeric field that starts with 1 and goes to 400, not unique, meaning there can be numerous 1's and only one 5 and so on. Hence, these were not autonumbers. Is there a syntax (or a way) to add one value to all such as change all 1's to 2's, all 2's to 3's, etc?

use the field calculator and add 1 to the values of the field ie in the python parser it would be

!YourFieldNameHere! + 1

That was super easy, thanks! I just switched to ArcMap from GeoMedia and was unsure of where to start. Thanks again!
