increment rows based on a record in postgresql

I have a query that returns the quantity and initial value and I want to turn this query into multiple rows by quantity.

Example:

Inquiry:

select 3 as numero, 10001 as valorinicial

Expected output:

 id | valor
 ----------

  1. 10001
  2. 10002
  3. 10003

Any suggestions with postgresql or postgresql / php ?
