    in 1it how do u say its decreasing

    eduncle-logo-app

    also is there any method shortcut to find whether its monotone or not

    eduncle-logo-app

    To check monotone behavior... It depends upon question and given data in it. But majorly if relation b/w xn and xn+1 is given then you can try by checking sign of xn+1-xn.

    yes you can check second question in the above attachment.

    eduncle-logo-app

    if xn+1-xn greater than or equal to zero than monotonic increasing and if less than or equal to zero than monotonic decreasing...
