B
1. Cross of high/low pairs.
C
1. Cross off high/low pairs. 2. Add the leftover numbers. 3. Divide the sum by 2.
D
1. Put the numbers in order. 2. Cross off high/low pairs. 3. Add the leftover numbers. 4. Divide the sum by 2.

Explanation

First put the numbers in order: 16, 18, 23, 24, 29, 30. Since there are six numbers, cross off the high/low pairs until the two middle numbers, 23 and 24, are left. Add them and divide by 2: (23 + 24) ÷ 2 = 23.5. So the correct sequence is to order the numbers, cross off pairs, add the leftovers, and divide by 2.
