Insert four geometric means between 4 and 128.
A) 9, 15, 33, 63
B) 10, 14, 34, 62
C) 8, 16, 32, 64
D) 8, 15, 33, 64

Question

Quizplus · Accepted Answer

The formula for finding the nth geometric mean between two numbers a and b is given by [(b/a)^(1/n)]*a. 
Applying this formula, we get:
First geometric mean: [(128/4)^(1/5)]*4 = 8
Second geometric mean: [(128/8)^(1/5)]*8 = 16
Third geometric mean: [(128/16)^(1/5)]*16 = 32
Fourth geometric mean: [(128/32)^(1/5)]*32 = 64

Therefore, option C is the correct answer.
