Santu Das   (x-1)*x*(x+1)=2730
(x*x*x)-x=2730.................................(1)
now 39/3=13 ; so the mid term will be 13, put x=13
then 42/3=14 ; put x=14 ; it satisfies eqn(1)
so mid term =14 hence sum =42

mousumi roy   lcm of 2730=2*3*5*7*13=13*14*15(because number are consecutive)
so the nos are=13,14,15
sum=13+14+15=42ans
