a(n) is formed by concatenating the next prime(n) primes.

Formula

The n-th term of the sequence is determined by grouping the prime numbers according to the natural order of primes themselves, e.g. the first prime is 2 so group the first two primes 2 and 3. Second prime is 3 so group the next 3 primes 5, 7 and 11, etc.
