Ahousing development was occupied by 12 people. during january 2016, 6 more people move into the development. during each subsequent month, 4 more people move into the development than moved in during the previous month. assuming nobody dies or moves out of the development, work out how many people occupy the development on 31 march 2017.

 30 people

Step-by-step explanation: So you start with 12 people

12+6= 18 because 6 more people moved in then an additional 12 move in because it doubles every month

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.
