Triangular numbers are the sum of the natural numbers up to a certain point. The triangular numbers less than 60 are 1, 3, 6, 10, 15, 21, 28, 36, 45, and 55. These numbers can be calculated using the formula ( T_n = \frac{n(n + 1)}{2} ), where ( n ) is a positive integer. The largest triangular number less than 60 is 55, which corresponds to ( n = 10 ).
