mean=8+32/2=20
.....hope it helps
but the answer is 16
Geometric mean of 8 and 32
L=a*r^(n-1)
L=32
a=8
n=3
32=8*r^(3-1)
32=8*r^2
r^2=32/8
r^2=4
r=sqrt4
r=+-2 ans.
Proof:
8,[16],32
8,[-16],32
L=a*r^(n-1)
L=32
a=8
n=3
32=8*r^(3-1)
32=8*r^2
r^2=32/8
r^2=4
r=sqrt4
r=+-2 ans.
Proof:
8,[16],32
8,[-16],32
sorry but mistake I wrote 20
what is this?
correct answer is 16 only
solution of the question
If three quantities are in Geometric Progression then the middle one is called the geometric mean of the other two.
Let, three numbers a, G and b are in Geometric Progression then, the middle number G is called the geometric mean between two numbers a and b.
⇔ a, G, b are in Geometric Progression
⇔ GaGa = bGbG = common ratio.
⇔ G22 = ab
⇔ G = ±√ab
