1.1 NUMBER SEQUENCE

• Number Sequence - is a list of numbers with pattern.
• Terms - It is the first number, a second number, and so on in a number sequence.
• Finite Sequence - A sequence having a finite number of terms.
• What type of sequence is presented in the picture? Finite or Infinite?

  Finite

  
• Infinite Sequence - A sequence that has an infinite number of terms
• Ellipsis - it is the indication that a sequence is infinite. It has a symbol of 3 dots (. . .).
