I don't think the OP wanted 20 and 40 which is why he is adding 10
rather than 9. I suspect the example is just an example and does not
represent the actual code he wants, in particular there is likely to
be an else block, and it that which he wishes to skip. I think the
answer to his question, however, is that there is no way to change the
index within the block in order to skip elements, so he will have to
use one of the suggestions made by others.
