The sum of the first 50 positive even integers is 2550. What is the sum E of even integers from 102 to 200 inclusive?  Pick.
A) 5100 B) 7550 C) 10100 D) 15500 E) 20100
My solution is:   First 50 even integers:   2   4   6   8   &lt;...&gt;   Integers from 102 to 200   102   104   106   108   &lt;...&gt;   We notice that each integer from the second set is 100 more than the respective integer in the first set. Since we have 50 even integers from 102 to 200, then:   E=2550+(100*50)=7550.7550
