Simplify. iv) Set the result in (iii) equal to the given total. v) Solve the equation in (iv) for the variable. vi) Review, in (i), the definition of the variable, and use this to find the four numbers. If you get stuck, please reply showing how far you have gotten in working through the steps. Thank you! Eliz.

If you add two odd integers - the sum is even. Adding four odd integers (consecutive or otherwise) cannot give an odd number.
