To find the average of the given numbers, we need to sum all the numbers and then divide by the total count of numbers. Here are the steps:

1. Sum the numbers.
2. Divide the sum by the count of numbers.

Given Numbers:

29,7 24,4 16,9 30,8 23,7 12,7 19,8 19,5 17,1 18,2 25 18,6 16,2 10,4 13,8 20,8 6,7 20,9 18,3 24,6 31 34,3 17,6 21,9 31,3 25,9 12,9 14 25,9

Step 1: Sum the Numbers

$29.7 + 24.4 + 16.9 + 30.8 + 23.7 + 12.7 + 19.8 + 19.5 + 17.1 + 18.2 + 25 + 18.6 + 16.2 + 10.4 + 13.8 + 20.8 + 6.7 + 20.9 + 18.3 + 24.6 + 31 + 34.3 + 17.6 + 21.9 + 31.3 + 25.9 + 12.9 + 14 + 25.9 = 593.8$

Step 2: Count the Numbers

There are 29 numbers.

Step 3: Calculate the Average

$\text{Average} = \frac{\text{Sum of Numbers}}{\text{Count of Numbers}} = \frac{593.8}{29} \approx 20.48$

Conclusion

The average of the given numbers is approximately 20.48.
