An arithmetic series consist of consecutive integers that are multiples of 4. whats the sum of the first nine terms of this sequence if the first term is 0?

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.
