There are three things in the code that are relevant: loop; print-variable; increment-value.

loop is do-while;

print-variable & increment-value: what Steven explained above.

So, as an example... with do-while loop, try printing...

1

2

3

4

If you can print that, then just increase the increment-value. Above its 1, and the question demands 2.

I have added exact answer, you can try first before checking that out.
