1 2 3 4 5 50

i think question is incorrect it has been asked what is the unit digt of tihs series and answer for that is 3
as 5! onwards unit digit is 0 and the sum of (1!+2!+3!+4!)=33 so unit digit is 3.....and if anyone know the answer of this then write the soln for that

look 50!(1/50! +2/50! +3/50!+........49!/50!+50!/50!)....neglecting higher terms as value is too small.....consider 50!(1/50+1)=50!*1.02=51!/50
