Primes with prime subscripts

Rule

Each term is: The nth prime, then the prime at that position

Known as: Primes with prime subscripts

The first 50 terms (starting from n=1) are:

3 5 11 17 31 41 59 67 83 109 127 157 179 191 211 241 277 283 331 353 367 401 431 461 509 547 563 587 599 617 709 739 773 797 859 877 919 967 991 1031 1063 1087 1153 1171 1201 1217 1297 1409 1433 1447

Example

To get the value for n=11:

  • Find the eleventh prime, giving 31.
  • Find the thirty-first prime, giving 127.

So the result is 127.
