CAN THIS SUM REALLY BE SOLVED ??????

Other sums of this type can be solved by recursion but this sum is something unusual...i can't find any recurrence relation.

@ Shirsha : Is this YOUR doubt or have you taken this sum from some book ?

hmm............we can do this like this,...

umm first no of st lines possible=ⁿC₂
then no of Î”s=^ⁿC₂C₃

giving Î”s

but this includes Î”s when the st lines r extended infinitely....
