Question

the product of three terms in g.p is 125/8;find g.m​

Answer 1

Answer:

terms are 1, 5/2, 25/4

Step-by-step explanation:

r= 5/2

Answer 2

Answer:

If r = 1.9732 then 3 numbers are 2.53 , 5 , 9.866

and If r = 0.5268 then 3 numbers are 9.5 , 5 , 2.634

Step-by-step explanation:

In this question,

We have been given that

Product of three numbers of G.P is 125 and sum of their products taken in pair is 87.

Let three numbers be  

Hence,Product of three number is 125

Therefore  

Since some of their products taken in pairs is 87.

Taking L.C.M we get,

Putting the value of a = 5 we get,

Using shridhanacharya formula we get,

Here b = -62 a=25 c = 25

On solving r = 1.9732 and 0.5268

if r = 1.9732 then 3 numbers are 2.53 , 5 , 9.866

and if r = 0.5268 then 3 numbers are 9.5 , 5 , 2.634
