# Searching for a noun

Sorry if this is grade 1 maths, but my mind is blank.

I'm trying to describe a way to specify a set of consecutive numbers.

Basically I'm thinking along the lines of:

StartingPoint + delta

e.g. 1000 "+" 3 is the set of numbers {1000, 1001, 1002, 1003}.

In the mathematical universe, is there a noun to replace "StartingPoint" and "delta" ?
