Answer 1

2+3+5+7+11+13/6=6.833

Answer 2

The mean of “first six prime numbers” is 6.83.

Solution:  

Prime numbers are the numbers which are divisible by ‘1’ and the ‘number itself’ and they should not be divisible by any other number.

In mathematics, the “first six prime numbers” are 2, 3, 5, 7, 11, and 13.

By formula, arithmetic mean of the series $=\frac{\text {Sum of the numbers in the series}}{\text {Number of entries in the series}}$

$\bold{M e a n=\frac{2+3+5+7+11+13}{6}}$

$=\frac{41}{6}=\bold{6.83}$.
