Answer: 45/28 or 1 17/28

Step-by-step explanation: First find a common denominator for your fractions so you can express them in a similar way so;

1/4= 7/28

9/14= 18/28

5/7=20/28

(7+18+20)/28= 45/28

Hello,

$x_{1} =1*1!=1\\
 x_{2} =2*2!=4\\
 x_{3} =3*3!=18\\
 x_{4} =4*4!=96\\

 S_{1} = x_{1}=1=2!-1\\
 S_{2} = x_{1}+x_{2}=1+4=5=3!-1\\
 S_{3} = x_{1}+x_{2}+x_{3}=5+18=23=4!-1\\
 S_{4} = x_{1}+x_{2}+x_{3}+x_{4}=23+96=119=5!-1\\

 \boxed{S_{n} = (n+1)!-1}\\
