Properties

Appears in sequences

• Upper prime of a record difference between it and the second prime before it.at n=31A031134
• Middle q of three consecutive primes p,q,r, such that one adjacent prime is near, the other is far and the ratio of the differences (whichever of (r-q)/(q-p) or (q-p)/(r-q) is greater than 1) sets a record.at n=27A084105
• Smallest prime q such that the gap between q and the previous prime is a perfect power that has not occurred earlier as a gap.at n=10A123996
• a(n) = nextprime(A138198(n-1)). Largest of a pair of consecutive primes whose prime gap is the first occurrence of n^2 or -1 if such a gap never occurs.at n=7A353085
