On the square roots of triangular numbers
By analogy with the square root of x, one can define the (positive) triangular root of x as the number n such that Tn = x: which follows immediately from the quadratic formula. So an integer x is triangular if and only if 8x + 1 is a square. Equivalently, if the positive triangular root n of x is an integer, then x is the nth triangular number.
