The sum of the first 50 positive even integers is 2550. What is the sum of the even integers from 302 to 400 inclusive?
Options:  A) 11,550  B) 14,550  C) 17,550  D) 20,550  E) 23,550
2 + 4 + 6 + 8 +...+ 100 = 2550   302 + 304 + ... + 400 = 50(300) + (2+4+...+100) = 15,000 + 2550 = 17,550   The answer is 17,550.
