[ an + an-1 + an-2 + ... + a1 ] - [ an-1 + an-2 + ... + a1 ] = an
would've been :p
If the user was that much smarter , I wouldn't have putted a simple solution
If same question is asked by any intellectual user here , I'll obviously raise my heights of answering
many factors are responsible while dealing any question
