Explanation
Prime number: A prime number is a number that can be divided only by one and the number itself.

Formula used:
The arithmetic mean = Sum of all terms/ Number of terms
Calculation:
According to the question,
First 10 prime numbers = 2, 3, 5, 7, 11, 13, 17, 19, 23, 29
The arithmetic mean = (2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29)/10
⇒ 129/10 = 12.9
The arithmetic mean of the first ten prime numbers is 12.9.
