Can somebody describe BINOMIAL THEOREM in a effective way....ABout the its "general term", "middle term" ...........thanks to anyone who will describe it

The following site describes it far better than I can:

 

http://mathworld.wolfram.com/BinomialTheorem.html

general term reffers to an common expression used.

 

middle term reffers to the centric term for a particular expression.

reffer this for greater explanition
