In finding the next three terms of a sequence you need to consider some steps such as finding the differences of the given terms, look for the relationship of the differences and the given terms...
Triangular Number Sequence. 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.
Find the sum of the following series : `1+3+6+10+15+…` to n terms.

26 Δεκ 2023 · A triangular number is a number that can be expressed as the sum of the first n consecutive positive integers starting from 1. The numbers form a sequence: 1, 3, 6, 10, 15, 21…. which continues till infinity. In the triangular number sequence: The first number is 1; The second number is (1 + 2) = 3
In this case you get $3 - 1 = 2$, $6 - 3 = 3$, $10 - 6 = 4$, at this point you will probably guess that the next difference will be $5$ and indeed it is: $15 - 10 = 5$. You can now get your sequence back by adding the numbers $1$, $2$, etc.
What is a Sequence? A Sequence is a list of things (usually numbers) that are in order. Infinite or Finite. When the sequence goes on forever it is called an infinite sequence, otherwise it is a finite sequence. Examples: {1, 2, 3, 4, ...} is a very simple sequence (and it is an infinite sequence) {20, 25, 30, 35, ...} is also an infinite sequence.
