This is NOT an arithmetic sequence because there is no common difference. It is a geometric sequence because there is a common ratio. Meaning that each term is a constant ratio or multiple of the previous term. The recursive rule for this geometric sequence is:
a(n)=3*a(n-1), a(1)=3
B=7
3(b-4)+5b=44
3b-12+5b=44
8b=44+12
8b=56
b=7
8 bra cause that’s the answer I got for sure
When there is only one number repeating, put it over 9
0.8 repeating is 8/9
if there was 2 numbers repeating (.232323), u would put it over 99....23/99
if there was 3 numbers repeating (.234234234), u would put it over 999...234/999
The surface are is about 161.6 square centimeters.
