A) A.P.
B) G.P.
C) H.P.
D) None of these
Correct Answer: B
Solution :
Let \[a\] and \[b\] be the same first and last terms of the three progressions, each having \[(2n+1)\] terms. Then the middle term of the A.P. is\[\frac{a+b}{2}\]. The middle term of the G.P. is\[\sqrt{ab}\]. The middle term of the H.P. is\[\frac{2ab}{a+b}\]. Obviously, these terms are in G.P.You need to login to perform this action.
