Ans 3.


(1+ 8 + 27 + ... + n3)/1-n


Since 13+23+33+...+n3 = (n(n+1))2/4   then


the expression becomes  (n(n+1))2/4(1-n4)


= ((n)2(n+1)2)/4(1-n4)


dividing the whole expression ny n4 . Now the expression is 


=(1)(1+1/n2))/4(1/n4-1)


= No since n->infinity 1/n tends to 0 thus byu using direct substitutions 


= 1/-4 =-1/4
