If a, b , c, d and p are distinct real numbers such that (a 2 +b 2 +c 2 )p 2 – 2(ab +bc +cd ) p + (b 2 +c 2 +d 2 ) ≤ ≤ 0 , then a, b, c, d are in
Text Solution
Verified by ExpertsThe correct answer is:
B
The given inequality can be re-written as
(ap – b) 2 + (bp – c) 2 +( cp – d) 2 ≤ ≤ 0
⇒ ⇒ ap – b = bp – c = cp – d = 0 ⇒ ⇒ 
⇒ ⇒ a, b, c, d are in G. P.
