4
Step-by-step explanation:
30-22=2x
8=2x
8/2=x
It's adding 7 each time. So...
5, 12, 19, 26, 33, 40, 47, 54, 61, 68, 75, and
82
Most of those are correct but the ones that are not are, (15+8 divided by 4-6) as division comes first. 6x3-8 as multiplication comes before subtraction. And 2/3+4x2, multiplication comes before addition. So change those couple up and you got it.
