a, b , ç are in G.P.
b² = ac
a, b, ç are in A.P
Refer to attachment!
According to question
b² = a × c
We are given that the Airthematic mean of a,b,c is b + 2
Last step we get by using (a - b)²
here , b/a is a integer
so here We will take A = 6 only because its given b/a is an integer
Now put value of a to find the answer
answer is a/b
rationalise i.e., multiply and divide with b+c if you didnt get anwer comment me. i you would try and send another type
answer:HelloGood AfternoonHave a great day
Hope this helps.
I guess you need to simplify the expression for z.
Given: b / a = c / b , or equivalently, ac = b².
I hope the image will help you
I think GP is the correct
no problem i'll tell it later on
