Find the common ratio of the following geometric sequence 2.512 11.304 50.868 228.906 1030.077?

Answer 1

Formula for the nth term of general geometric sequence

tn = t1 x r(n - 1)

For n = 2, we have:

t2 = t1 x r(2 - 1)

t2 = t1r substitute 11.304 for t2, and 2.512 for t1 into the formula;

11.304 = 2.512r

r = 4.5
