Question

what is the common difference for the geometric sequence 4, 12, 36

Answer 1

I really need help here

Answer 2

A geometric sequence is of the form
\[a, ar, ar^2...ar^n\]
Two consecutive terms are in the same ratio
that is
\[\frac{ar}{a}=\frac{ar^2}{ar}=\frac{ar^3}{ar^2}=r\]
here r is the common difference or ratio
so
here we have 4, 12 and 36
so
\[\frac{12}{4}=\frac{36}{12}\]
Can you find this?
