Find two geometric means between 7 and 875.

Question

anonymous · Answer

you have to write it like this

7/x = 875/x

wherein X is the geometric mean
To find X use cross multiplication. It's just simple algebra

anonymous · Answer

oh sorry the right equation will be 

7/x= x/875

anonymous · Answer

those are the geometric means?

anonymous · Answer

The value you will get for X is the geometric means

amistre64 · Answer

essentially youre creating a geometric sequence

amistre64 · Answer

a1 = 7 and a4 = 875

find a2 and a3

amistre64 · Answer

an = a1 r^(n-1)

a4 = 7 r^3 = 875

r = (875/7)^(1/3)

a2 = 7 * (875/7)^(1/3)

a3 = 7 * (875/7)^(2/3)

if i see it right

amistre64 · Answer

otherwise you can try to solve:$$\frac{7}{a_2}=\frac{a_2}{a_3}=\frac{a_3}{875}$$
