What the three missing terms after22,28,21,27,20,26,19

25, 18, 24

Step-by-step explanation:

the pattern is up 6, down 7, so 19+6=25, then 25-7=18 and finally 18+6=24

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
