There exists infinitely many triangular numbers that are prime.
The triangular numbers are defined by adding n positive integers together. For example the first triangular number is 1 the next one is 3. The one after that is 6. So the triangular numbers are defined as 0+1=1
1+2=3
1+2+3=6

As always I welcome the readers to try and prove or disprove this conjecture.

This has been disproven due to the fact the formula for the nth triangular number factorizes, therefore, no more primes can exist of this form.
