The first 19 triangular numbers are the sums of the first ( n ) natural numbers, calculated using the formula ( T_n = \frac{n(n + 1)}{2} ). They are: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91, 105, 120, 136, 153, 171, and 190. Each number represents a triangle with dots, where ( n ) indicates the number of rows.

Which numbers are both triangular and square?
The numbers that are both triangular and square are known as "triangular square numbers." The first few of these numbers are 1, 36, and 1225. They can be generated by solving the equation ( n(n + 1)/2 = m^2 ) for positive integers ( n ) and ( m ). The general formula for finding these numbers involves using the Pell's equation related to the sequence of triangular numbers.
