Question
If a1, a2, a3 , 5, 4, a6, a7, a8, a9 are in H.P. and D = 
then the value of [D] is
(Where [.] represents, the greatest integer fn.)
then the value of [D] is (Where [.] represents, the greatest integer fn.)
Options
A.0
B.1
C.2
D.3
Solution
D = 
are in A.P.
d =
⇒ 
an =
Hence D =
R1 → R1 - R2 and R2 → R2 - R3
⇒ [D] = 2 (Sol)
are in A.P.d =
⇒ an =
Hence D =
R1 → R1 - R2 and R2 → R2 - R3
⇒ [D] = 2 (Sol)Create a free account to view solution
