Arithmetic Sequence ||Find the term, when first term and common difference are given

Arithmetic sequence and key facts

  • An arithmetic sequence is a sequence where the difference between consecutive terms is always the same(i.e constant).This constant is called the common difference.
  • An arithmetic sequence is one which begins with a first term (a) and where each term is separated by a common difference (d). e.g. 3, 5, 7, 9, 11, ...
  • The nth term of an arithmetic sequence is given by tn = a + (n - 1)d
