Half double treble crochet

Hi,
I can’t find an exact description of the half double treble crochet anywhere.
You start with 5 loops on the hook.
  Do you then yarn over and pull through 2 loops, yarn over and pull through another 2 loops, and then pull through the remaining three loops?
Or
do you yarn over and pull through 2 loops and then pull through the remaining 4 loops?
It would be great if someone could let me know briefly.
Thank you very much.....

Hello, unfortunately I couldn’t find anything either, but: for the half double crochet you work 3 stitches off together, and for the half treble crochet you also work the last 3 stitches off together, following the half double crochet. It’s in the big video collection. 
So I’d guess that for the half double treble crochet, you also work off the last 3 stitches together.
Best, Bea

Hi Bea,

Thank you so much for your reply. In the meantime, I asked the publisher of the book with the crochet pattern. You’re right. The half double treble crochet is worked exactly as you described: first, pull through two loops; then pull through another two loops; and finally, pull through the last three loops.
Thanks again...
Best regards, Birgit
