There are (4n+1) terms in a certain sequence of which the first (2n+1) terms form an A.P of common difference 2 and the last (2n +1) terms are in G.P. of common ratio `1//2`. If the middle term of both A.P and G.P. are the same , then find the mid-term of this sequence.

A

`(n.2^(n+1))/(2^(n)-1)`

B

`(n.2^(n+1))/(2^(2n-1))`

C

`n.2^(n)`

D

none of these
