Let a,b,c (a < b < c) be in AP ; a 2 , b 2 , c 2 are in GP and a + b + c = 3/2 ; then a =
A
B
C
D
None
Text Solution
Verified by ExpertsThe correct answer is:
C
a + b + c = 3b = 3/2 ∴ b =1/2
∴ a = 
– d & c = 
+ d
Now ( 
– d) 2 , 
, ( 
+ d) 2 are in GP
∴ (using b 2 = ac) ⇒ 
= d 2 – 
⇒ d = 1/ 
∴ a = 
– d = 
– 
=
