A geometric sequence is defined recursively by a(1)=40 and a(n)=a(n-1)*(1/2). a) write out the first four terms of the sequence

b) is the 9th term of this sequence larger or smaller than 1/10? show the calculation that you use to determine your answer.

(23*2)-12=x     x=34

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

first one because it can't have a fraction in it

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.
