1/6 n(n+1)(n+2)
A triangular number counts the objects that can form an equilateral triangle. 121 is not a triangular number, though 120 is.
A single number, such as 8163264, does not form a sequence.
A triangular number is a member of the series which is calculated as follows: t(1) = 1 = 1 t(2) = 1 + 2 = 3 t(3) = 1 + 2 + 3 = 6 t(4) = 1 + 2 + 3 + 4 = 10 and so on. t(n) = 1 + 2 + 3 + 4 + ... + n Fortunately, there is a simpler formula t(n) = n*(n+1)/2 To see why they are called triangular numbers, consider the following pattern: Put one mark in the middle of a line. Then, in the line underneath, put 2 marks. You now have three [=t(2)] marks in the form of a triangle. x x x In the next line, put three marks. You now have six [=t(3)] marks in the form of a triangle. x x x x x x and so on.
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form as: 64,100,000
A triangular number counts the objects that can form an equilateral triangle. 121 is not a triangular number, though 120 is.
It is a sequence in which the numbers represent the number of spheres in a pyramidal stack of spheres. There are a number of possible configurations for stacking spheres - a visit to fruit stalls may show you options. The square based pyramidal numbers are given by the sums of the first n square numbers. So U(1) = 1^1 = 1 U(2) = 1^2 + 2^2 = 1 + 4 = 5 and so on U(n) = 1^2 + 2^2 + ... + n^2 = n(n+1)(2n+1)/6. However, there are also triangle based pyramidal numbers and hexagon based pyramidal numbers, since these configuration also give stable stacks.
There is no such thing as a "triangular" number (as a number), a triangular number or triangle number counts the objects that can form an equilateral triangle. One object can and Three objects can but not Two objects.
Ziggurats were temples of Sumerian origin in the form of pyramidal towers, consisting of a number of levels.
One number, such as 51014151720354850, does not form a sequence.
A crystal is a mineral where all of the atoms are in a row, this is what makes it kind of clear. What determines its shape is the amount of space it has to form in and will usually have triangular pyramidal edges.
A triangular number or triangle number counts the objects that can form an equilateral triangle. 10 objects can be formed into an equilateral triangle.
I am pretty sure that theshining star sequence is another form of the octagonal number sequence.
Triangular number: An integer of the form (1/2)n(n + 1), where n is a positive integer.12 is not a triangular number. The first few triangular numbers are 1, 3, 6, 10, and 15.

No. Pyramids is a plural noun. The adjective form would be pyramidal.
The molecular geometry of phosphorus trichloride (PCl3) is trigonal pyramidal. This means that the phosphorus atom is bonded to three chlorine atoms, with the lone pair of electrons creating a pyramidal shape.
