Question: 93

5. In a list of consecutive odd integers, the second number can be represented by x. The first number in the list could be represented by

A. x - 3
B. x - 2
C. x - 1
D. x + 1
E. x + 2

Correct Answer: B

Explanation:

B. Don't fall into the old "odd-integers trap!" Even though the numbers are odd, they still must differ by 2. (If you don't believe me, think of 3, 5, 7 . . . .) Because the question tells you that the second number is x, the first one must be 2 less than x, or x - 2.
