Geometric solution

Question

Insert 4 numbers between 32 and 243 so that the resulting sequence is geometric

Answer 1

The sequence is like this

32,32r, 32r^2,32r^3,243

In a Geometric series the ratio between adjacent elements are same.

 

32*r/32=243/(32r^3)

r^4=243/32

r=1.66  you can verify the answer by constructing the geometric sequence.

All the best

Thank you
