  2. GRE Mathematics Test - Wikipedia

    en.wikipedia.org/wiki/GRE_Mathematics_Test

    The GRE subject test in mathematics is a standardized test in the United States created by the Educational Testing Service (ETS), and is designed to assess a candidate's potential for graduate or post-graduate study in the field of mathematics. It contains questions from many fields of mathematics; about 50% of the questions come from calculus ...

    en.wikipedia.org/wiki/Graduate_Record_Examinations

    Changes to the GRE took effect on November 1, 2007, as ETS started to include new types of questions in the exam. The changes mostly centered on "fill in the blank" type answers for the mathematics section that requires the test-taker to fill in the blank directly, without being able to choose from a multiple choice list of answers.

  4. Erdős conjecture on arithmetic progressions - Wikipedia

    en.wikipedia.org/wiki/Erdős_conjecture_on...

    Because the sum of the reciprocals of the primes diverges, the Green–Tao theorem on arithmetic progressions is a special case of the conjecture. The weaker claim that A must contain infinitely many arithmetic progressions of length 3 is a consequence of an improved bound in Roth's theorem. A 2016 paper by Bloom [4] proved that if {,..

  5. Generalized arithmetic progression - Wikipedia

    en.wikipedia.org/wiki/Generalized_arithmetic...

    In mathematics, a generalized arithmetic progression (or multiple arithmetic progression) is a generalization of an arithmetic progression equipped with multiple common differences – whereas an arithmetic progression is generated by a single common difference, a generalized arithmetic progression can be generated by multiple common differences.

  6. 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. The constant difference is called common difference of that ...

  7. Portal:Arithmetic - Wikipedia

    en.wikipedia.org/wiki/Portal:Arithmetic

    Plot of y = 3 √ x.The plot is symmetric with respect to origin, as it is an odd function.At x = 0 this graph has a vertical tangent. In mathematics, a cube root of a number x is a number y that has the given number as its third power; that is =.

  8. Salem–Spencer set - Wikipedia

    en.wikipedia.org/wiki/Salem–Spencer_set

    Salem–Spencer sets are also called 3-AP-free sequences or progression-free sets. They have also been called non-averaging sets, [ 1 ] [ 2 ] but this term has also been used to denote a set of integers none of which can be obtained as the average of any subset of the other numbers. [ 3 ]

  9. Multiple choice - Wikipedia

    en.wikipedia.org/wiki/Multiple_choice

    A multiple choice question, with days of the week as potential answers. Multiple choice (MC), [1] objective response or MCQ(for multiple choice question) is a form of an objective assessment in which respondents are asked to select only the correct answer from the choices offered as a list.
