Re: What comes next?
I think you may have got #1 and #10 wrong (they should be the same answer).
On reflection, I should have posed #7 as
7, 15, 8, 7, 10, 19, ?
Which may help!
All the rest are correct.

Re: What comes next?
Ah, yes, that makes #7 a lot easier! No excuses for getting 1 and 10 wrong - missed a step for #1 and some spectacularly bad counting for #10
