How do you say multiples of some number?

Question

On a specification about a data. The valid value must be multiples of 10 (10, 20, 30, ...)

How do you state that in Japanese. I saw on a document that it is written as

Xは10,20,30・・のように10飛で付番する

Is there other way to state this in Japanese?

Note that "multiple of 10" and "10飛び" are not the same. For example, the sequence "2, 12, 22, 32, 42, ..." is not "multiples of 10" but is "10飛び".
@sawa. Arithmetic progression! What about geometric progression as in 2^1, 2^2, ...2^n ? What's that called?
@Flaw I don't know of a conventional way of saying it. I can only describe it as 等比数列.
