Question

Find the common ratio of the geometric sequence:
1.2, 0.84, 0.588, 0.4116

Answer 1

Common ratio = .84 /1.2 = 7/10

Answer 2

or 0.4116/0.588= 7/10

Answer 3

Common Ratio is always a constant.
common ratio will give the same result in any case second term / first term,third term /second term ,fourth term/third term .....

Answer 4

0.4116=1.2*r^(4-1)
0.4116/1.2 =r^3\[r=\sqrt[3]{0.343}=0.7\]

Answer 5

No need to apply tn = a r^(1-n)

r you can get directly as i said

Answer 6

many way to solve

Answer 7

I know this is offtopic, but is this advanced geometry or calculus 2?
