For every positive integer n, the nth term of sequence is given by an= 1/n - 1/(n+1). What is the sum of the first 75 terms?	Select the correct option.
A) 25/26 B) 40/41 C) 75/76 D) 150/151 E) 151/75
a1 = 1 - 1/2   a2 = 1/2 - 1/3   a3 = 1/3 - 1/4   etc...   a75 = 1/75 - 1/76   The sum of these terms is 1-1/76 = 75/76   The answer is 75/76.
