2 out of 3. :)

And here's the third one: 83. It's a straight-up "add the next number"--except that if your number is in the sequence, you skip it. Hence, 1+2=3, but since 3 is in the system, you go to 3+4=7, 7+5=12, 12+6=18, but you add 18+8 because 7 is in the sequence. So, after 56+13=69, you go 69+14=83.

Well, 2 and 3 seemed very familiar--it wasn't "oh, I remember this puzzle, I know the answer," but it was more like "OK, I think there's a trick in 3--what else can it be? Of course" and "2...haven't I seen this before? Don't remember. One, then two ones--wait, that next one is 'two one'..."

As to 1, I'd determined the addition pattern easily enough, and I was just saying to myself "why are three, seven, and twelve skipped--wait, three, seven, and twelve? Of course."

That's pretty tricky. Nice.
