Question
Transcribed Image Text: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.
