The mean is usually the arithmetic mean - there are other means in maths. For a set of numbers, the arithmetic mean is the sum of the numbers divided by the number of numbers.

There is no simple answer because there is no simple rule for primes: it is certainly NOT an arithmetic progression.

Harmonic progressions is formed by taking the reciprocals of an arithmetic progression. So if you start with some number a, and add a common difference d each time, the arithmetic progression would be a, a+d, a+2d, a+3d etc. The harmonic progression comes from taking the reciprocals of these terms. So we have a, a/(1+d), a/(1+2d), a/( 1+3d)... Here is a harmonic progression: 1/6, 1/4, 1/3, ....
