What are triangular numbers? Definition, Types and Importance maths AESL
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.

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.
