The series of differences between consecutive prime numbers is represented as dp1, dp2, dp3, .... dpn .Whare dp1 is the difference between the second and the first prime number. Find the sum of series when n = 23, given that the 23rd prime number is 83 ? Choose the correct choice from the following answers
A) 81 B) 82 C) 83 D) 87 E) 86
S1 = 1 when last prime number is 3   S2 = 3 when last prime number is 5   S3 = 5 when last prime number is 7 and so on.   So the sum of the series is 2 less than the last prime number.   So S23 = 83 - 2=
