Question

The sum of three consecutive odd integers is -27.
A. {-7, -9, -11}
B.{-10,-9,-8}
C.{-5,-9,-13}
D. {-11,-13,-15}

Answer 1

A method to prove if the statement is true is by trial and error method. Since we are already given different sets of values, we can try to see if they match the given conditions: (consecutive, odd integers):

Looking at the choices:

A. consecutive odd integers (OK)
(-7) + (-9) + (-11) = -27

Since the integers in choice A match the statement, then choice A is the correct answer.
