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.

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.
Step 1: Enter the terms of the sequence below. The Sequence Calculator finds the equation of the sequence and also allows you to view the next terms in the sequence. Arithmetic Sequence Formula: a n = a 1 + d (n-1) Geometric Sequence Formula: a n = a 1 r n-1. Step 2: Click the blue arrow to submit.
1,3-bis (aminomethyl)cyclohexane (1,3-BAC) are a collection of organic compounds with the formula C6H10(CH2NH2)2. The compounds belong to the sub class cycloaliphatic amine. Their key use is as an epoxy resin curing agent.
For example, each number in the sequence 1, 3, 6, 10, 15… gives the number of dots in a growing pattern of triangular arrays. In this growing pattern, you can also see that the number of dots increases by successive whole numbers.
