strong primes

A prime is said to be strong if it larger than the average of the two surrounding primes

For example, 17 is a strong prime since it is greater than the average of the two surrounding primes 13 and 19.

Primes which are neither balanced nor strong are called weak primes.

The first run of 1,2,..., 12 consecutive strong primes starts at 11, 37, 1657, 1847, 74687, 322193, 5051341, 11938853, 245333213, 397597169, 130272314657, and 1273135176871, respectively.

The first strong primes are 11, 17, 29, 37, 41, 59, 67, 71, 79, 97, 101, 107, 127, 137, 149, 163, 179, 191, 197, 223, 227, 239, 251, 269, 277, 281, 307 more terms
