Two geometric means are inserted between 4 and 864 so the four numbers form a geometric sequence. what are these two numbers ?

24 and 144

Step-by-step explanation:

a = 4

t4 = 864

864 = 4*r^(4 - 1) divide by 4

216 = r^3            Take the cube root of 216

6 = r

Note you can find the cube root of any number by using your calculator.

t2 = a * r^(2 - 1)

t2 = 4 * 6^1

t2 = 24

t3 = a*r^(3 -1)

t3 = 4 * 6^2

t3 = 4 * 36

t3 = 144
