[5 (3) 2] ... [26 (28) 6] ... [22 (30) 12]
add the outer numbers, then subtract 4
5+2-4=3
26+6-4=28
22+12-4=30

1st number - 2x2nd number + 11
21-2+11=30
20-20+11=11
16-4+11=23

Re: Tricky Numbers Please
Another possible answer to:
21 (30) 1 20 (11) 10 16 (?) 2
21/1=21 21+9=30
20/10=2 2+9=11
so 16/2=8 8+9=17
I really dislike these ones where there are 2 or more valid answers...
