Problem: the sum of the first 50 positive even integers is 2550 . what is the sum q of even integers from 102 to 200 inclusive ?
Rationale: "my solution is : first 50 even integers : 2 4 6 8 < . . . > integers from 102 to 200 102 104 106 108 < . . . > 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 : q = 2550 + ( 100 * 50 ) = 7550 . b"
annotated_formula: multiply(divide(add(200, 102), const_2), add(divide(subtract(200, 102), const_2), const_1))
