  2. Geometric series - Wikipedia

    en.wikipedia.org/wiki/Geometric_series

    The geometric series is an infinite series derived from a special type of sequence called a geometric progression.This means that it is the sum of infinitely many terms of geometric progression: starting from the initial term , and the next one being the initial term multiplied by a constant number known as the common ratio .

  3. Geometric progression - Wikipedia

    Diagram illustrating three basic geometric sequences of the pattern 1(r n−1) up to 6 iterations deep.The first block is a unit block and the dashed line represents the infinite sum of the sequence, a number that it will forever approach but never touch: 2, 3/2, and 4/3 respectively.

  4. Geometry of numbers - Wikipedia

    en.wikipedia.org/wiki/Geometry_of_numbers

    In the geometry of numbers, the subspace theorem was obtained by Wolfgang M. Schmidt in 1972. [6] It states that if n is a positive integer, and L 1,...,L n are linearly independent linear forms in n variables with algebraic coefficients and if ε>0 is any given real number, then the non-zero integer points x in n coordinates with

  5. Arithmetic progression - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_progression

    Proof without words of the arithmetic progression formulas using a rotated copy of the blocks.. An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence.

  6. Euclidean geometry - Wikipedia

    en.wikipedia.org/wiki/Euclidean_geometry

    Euclidean geometry is a mathematical system attributed to ancient Greek mathematician Euclid, which he described in his textbook on geometry, Elements.Euclid's approach consists in assuming a small set of intuitively appealing axioms (postulates) and deducing many other propositions from these.

  7. Geometric mean - Wikipedia

    en.wikipedia.org/wiki/Geometric_mean

    Example of the geometric mean: (red) is the geometric mean of and , [1] [2] is an example in which the line segment (¯) is given as a perpendicular to ¯. ′ ¯ is the diameter of a circle and ¯ ′ ¯.
