sequence, in mathematics, is a string of objects, like numbers, that follow a particular pattern. The individual elements in a sequence are called terms. Some of the simplest sequences can be found in multiplication tables:

  • 3, 6, 9, 12, 15, 18, 21, …
  • To write the sequence of square numbers, lets add increasing odd numbers to get the next number 1,4,9,16, 25…
  • Fibonacci sequence, start with 1, 1,… and every new number is the sum of the two previous numbers:
