Answer:
33
Step-by-step explanation:
Arrange number in numerical order (least to greatest)
22, 26, 29, 33, 35, 39, 42,
Cross out a number from each side until there's one number left, in this case, it would be 33. This would only work if there is an even amount of numbers.
If there is an odd amount of numbers then do the previous steps and there would be two numbers left. Add them then divide by 2 and you've got your answer.
