Topics in Progressions

1

Arithmetic Progression: Core Idea

  • An Arithmetic Progression is a list of numbers in which each term after the first is obtained by adding a fixed number to the preceding term.
  • The fixed number is called the common difference.
  • An AP can be finite or infinite.
2

Nth Term of an Arithmetic Progression

  • The nth term of an AP gives any term directly without writing all earlier terms.
  • If there are n terms in the AP, then the nth term is also the last term, sometimes denoted by l.
  • The formula is used in salary growth, distances, savings, and counting terms in a sequence.
3

Sum of First n Terms of an Arithmetic Progression

  • The sum of terms in an AP can be found quickly without adding each term one by one.
  • The Gauss pairing idea shows how sums can be simplified by pairing first and last terms.
  • There are two useful sum formulas: one using a and d, and one using a and l.
4

Geometric Progression: Core Idea and nth Term

  • A Geometric Progression is a list in which each term after the first is obtained by multiplying the preceding term by a fixed non-zero number.
  • The fixed number is called the common ratio.
  • A GP requires a not equal to 0, r not equal to 0, and r not equal to 1.
