1 2 3 50

1!+2!+3!+..........+50!
50!((1!/50!)+(2!/50!)+(3!/50!).....+(48!/50!)+(49!/50!)+(50!/50!))
The terms upto (48!/50!) can be neglected because the values will be very small
50!((49!/50!)+1)
50!((1/50)+1)
50!(51/50)
Therefore the ans will be 51!/50

taking 50! common
50!(1/50! + 2/50! +........+ 50!/50!)
all the terms in bracket will be neglected as the values will b very small (including 49!/50!)
therefore ans= 50!

please sumone explain the techniques for solving this question

ansr is
3.1035*10^64
11 years agoHelpfull: Yes(5) No(5)
formula is->
n+1!/n
hence in this series is going upto 50 terms thus,51!/50

answer will be just greater than 50!...choose according to options given in the question...

what formula can we use here????
11 years agoHelpfull: Yes(0) No(0)
ans will be some more than 50!
11 years agoHelpfull: Yes(0) No(0)
51!-1
will be derived !!!
