In number 2, a row is added with two dots to the first number
In number 3, a row is added with three dots to the second number
Again, in number 4, a row is added with four dots to the third number and so on
So the sequence formed here is in the pattern:
1, 1 + 2, 1 + 2 + 3, 1 + 2 + 3 + 4, and so on.

Amount of Triangular Numbers

In the example of three-sided numbers you will see, the following number in the arrangement is added with an additional line. Allow us to clarify in detail.

First number is 1

In number 2, a column is added with two specks to the primary number

In number 3, a line is added with three specks to the subsequent number

Once more, in number 4, a line is added with four specks to the third number, etc

So the grouping shaped here is in the example:

1, 1 + 2, 1 + 2 + 3, 1 + 2 + 3 + 4, etc.
