-150, -148 To find these numbers set up an algebraic expression. The first even integer would be 2X and the next even integer would be 2X + 2 So, 2X + (2X+2) = -298 Solving for X, X = -75 So the first even integer would be 2*(-75) or -150 And the second even integer would be 2 + the first or 2+-150 or -148
In a fraction, the numerator represent the part out of the denominator which represents the total. Neither need be rational (or even real).
n + 1
No. For any integer, you can add one to get an even greater integer.
2n + 2 = 2(n+1)
