This is the Triangular Number Sequence: 1, 3, 6, 10, 15, 21, 28, 36, 45, ... 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.

Triangular numbers are a type of figurate number, other examples being square numbers and cube numbers. The n th triangular number is the number of dots in the triangular arrangement with n dots on each side, and is equal to the sum of the n natural numbers from 1 to n.
The triangular number sequence is the representation of the numbers in the form of equilateral triangle arranged in a series or sequence. These numbers are in a sequence of 1, 3, 6, 10, 15, 21, 28, 36, 45, and so on. The numbers in the triangular pattern are represented by dots.
1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78… is a triangular number pattern. If we examine the pattern, we can say that the nth number in the triangular number pattern is the sum of all numbers from 1 to n. That is, the 6th number in the triangular pattern is the sum of all numbers from 1 to 6, i.e., $1 + 2 + 3 + 4 + 5 + 6$ or $21$.
Numbers can have interesting patterns. Here we list the most common patterns and how they are made. Arithmetic Sequences. An Arithmetic Sequence is made by adding the same value each time. Example: 1, 4, 7, 10, 13, 16, 19, 22, 25, ... This sequence has a difference of 3 between each number.
2 ημέρες πριν · Triangular numbers can be represented by arranging a pattern of dots in an equilateral triangle with the same number of dots on both sides. In triangular numbers, the first is 1, the second is 3, the third is 6, the fourth is 10, the fifth is 15, and so on.
