The sequence x1, x2, x3,..., is such that Xn = 1/n - (1/(n+1)). What is the sum of the first 3 terms of the sequence?  Choose the correct choice from the following choices
A) 201/100
B) 99/100
C) 100/101
D) 1/10000
E) 3/4
3/4asy task and accomplish   X1=1-1/2   x2=1/2-1/3   x3=1/3-1/4   sum=X1+X2+X3=1-1/2+1/2-1/3+1/3-1/4= 3/4   3/4 is the answer
