Is there a way that I can start an enumerate numbering at, say 17, then have the succeeding item numbers automatically add 2 to the preceding one? Say, I want to typeset the answers to the odd-numbered exercises starting from 17, I want my list to show
17. answer 17 19. answer 19 21. answer 21 23. answer 23 . . .
I know that this can be done manually but after a while, typing the item numbers manually can become bothersome.
Edit I put the list in the code environment to prevent automatic renumbering.
