Questions and Answers

What is the definition of a quadratic sequence?

  • A sequence of numbers where the first difference between consecutive terms is constant.
  • A sequence of numbers where consecutive terms are quadratic.
  • A sequence of numbers where each term is a quadratic expression.
  • A sequence of numbers where the second difference between any two consecutive terms is constant. (correct)

    • What is the general form of the nth term of a quadratic sequence?

  • Tn = an^2 - bn + c
  • Tn = an + bn^2
  • Tn = an^2 + bn + c (correct)
  • Tn = an^3 + bn + c

    • How can we find the values of a, b, and c in a quadratic sequence?

  • By using the formula for the nth term of an arithmetic sequence
  • By finding the common difference between consecutive terms
  • By solving simultaneous equations derived from the general form (correct)
  • By plotting a graph of the sequence
