What are triangular numbers? Triangular numbers are numbers that can be represented as a triangle. The numbers form a sequence known as the triangular numbers. The first triangular number T_ {1}=1 T 1 = 1. The second triangular number is found by adding 2 2 to the previous one. So, T_ {2}=1+2=3. T 2 = 1 + 2 = 3.

What are Triangular Numbers? Triangular numbers are usually represented as a sequence of numbers created by organising rows of dots into equilateral triangles. In other words, this means that if you were drawing triangles that got bigger by one equal row of dots at a time, you would count the dots that appear both inside and outside the triangle.

It is simply the number of dots in each triangular pattern: By adding another row of dots and counting all the dots we can find the next number of the sequence. The first triangle has just one dot. The second triangle has another row with 2 extra dots, making 1 + 2 = 3 The third triangle has another row with 3 extra dots, making 1 + 2 + 3 = 6
