Question

Two geometric means are inserted between 6 and 384 so the four numbers form a geometric sequence. What are these two numbers?

Hint: an = a1(r)n − 1, where a1 is the first term and r is the common ratio

Answer 1

a1 r^3 = 384
a1 = 6

so r^3 = 384/6 = 64

now you need to find r
r = cube root of 64 = ?

Answer 2

do you follow the above?

Answer 3

Yes thank you!
