Learn the definition of triangular numbers. See the triangular numbers formula and the triangular numbers list, and learn the sum through examples.
The triangular numbers form a type of quadratic sequence. The nthnthnth term of the sequence is, Tn=12n(n+1).Tn=12n(n+1).Tn=21n(n+1). To calculate a term within the sequence of triangular numbers, we substitute the position of the term into the nthnthnth term (this would be the...
When certain numbers of dots are arranged into equilateral triangles as follows, these are triangular numbers: Triangular numbers do not appear in the primary-school national curriculum for maths, but they are taught at secondary school and may be taught to very able Year 5 or 6 children. A c...
The following theorem is proved in the paper: "Let y 1 ,···,y s be a multiplicative independent system of unimodular complex algebraic numbers and let θ k be real numbers defined by y k =e 2πi k (k=1,···,s). Set =( 1 ,···, s )... P Kiss,RF Tichy - 《Procee...

Example of numbers. A place value chart is a helpful tool used to interpret the number system. The chart, also known as a table, is used to find the value of each digit of a number. What does a place value chart look like? A couple of place value charts can be helpful representation...
the triangular number sequence is the representation of the numbers in the form of anequilateral triangle. The pattern formed by the triangular numbers is such that the sum of the previous number and the order of the succeeding number results in the sequence of triangular numbers. In other words...
