If you are counting by twos starting at zero, what comes after 18?

• A. 19
• B. 20
• C. 21
• D. 22

Answer: (B)

To determine what comes after 18 when counting by twos starting at zero, we look at the sequence generated by this counting method. When counting by twos from zero, the sequence is: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, and then we add two more to 18. Adding 2 to 18 gives us 20 as the next number in the sequence. The counting pattern continues in increments of two, so 20 follows directly after 18. This demonstrates a clear and consistent pattern as each number in this counting sequence is two more than the previous one. Hence, after reaching 18, the next number when counting by twos is indeed 20.
