Answer:
27
Explanation:
organize the ages in order from least to greatest
17, 18, 21, 22, 25, 29, 34, 45, 56, 62
from both sides, eliminate one until you get to the middle.
Because there's an even number, you will end up with two numbers, 25 and 29. Find the middle of those two numbers...
25, 26, 27, 28, 29
