is there a prime equal to its position in the sequence of primes?
if i understand what youre trying to say, no because any prime is strictly larger than its position # since most numbers arent primes
i.e. p_1 = 2 > 1
p_2 = 3 > 2
p_3 = 5 > 3

Kek, OP did not think 5 seconds before posting.

Really dude? How in the hell would that even work?
>>8572815
Even if every number after 2 was prime, it would still be impossible as the position of prime p would be p-1
Now let's prove the conjecture.
Assume for induction p_k > k for some k
p_1 = 2 > 1 is the base case
p_n+1 > p_n
p_k+1 > p_k > k
Since all primes are by definition integers and k is an integer
p_k+1 > p_k >= k+1
p_k+1 >= k+1
So by induction p_n > n

Woops last line should be p_k+1 > k+1
