No. The first few triangular numbers are 1, 3, 6, 10, 15, 21, 28, ...
The first six triangular numbers are : 1,3,6,10,15,21. However, sometimes the first triangular number is regarded as 0 (zero) so you then have 0,1,3,6,10,15 as the first six triangular numbers.

Carl Friedrich Gauss did not discover triangular numbers, but he is known for his early work with them as a child. At the age of 8, he famously summed the first 100 integers quickly by realizing that they could be paired to form triangles. The concept of triangular numbers, which are the sums of the first ( n ) natural numbers, has been known since ancient times, long before Gauss's contributions in the late 18th century.
