Question

If \( q \) is a positive integer, which of the following is an even positive integer?

• A. \( 2q + 1 \)
• B. \( 2q \)
• C. \( 2q + 3 \)
• D. \( 2q + 5 \)

Hint:

An even number is always divisible by 2. An odd number is of the form \( 2n + 1 \).

Answer 1

The Correct Option is B

An even number is of the form \( 2n \), where \( n \) is an integer.
- \( 2q + 1 \) is odd.
- \( 2q \) is even.
- \( 2q + 3 \) is odd.
- \( 2q + 5 \) is odd.
Thus, \( 2q \) is the correct answer.
