+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.The Gen term can be written as 1/(4n-3)(4n-2)(4n-1)
Split it and do same manipulation to create a form where u can get the 1-1/2+1/3.. thing
how do u get this
by observing the pattern of the each term of individual term like 1,5,9 and then 2,6,10
They are all in ap with the respective term of next one
