Sequences Vocabulary

• sequence - an ordered list of numbers

• term - each number in a sequence

• arithmetic sequence - each term is found by adding the same number to the previous term

In an arithmetic sequence...

• the terms can be whole numbers, fractions or decimals

• 
  

• 
  

Describe the relationship between the terms in the arithmetic sequence 8, 13, 18, 23, ... . The write the next THREE terms in the sequence.

• Continue the pattern to find the next THREE terms

• The pattern is +5

• The next THREE terms are - 38, 33 & 38

Describe the relationship between the terms in the arithmetic sequence 0.4, 0.6, 0.8, 1.0, ... . The write the next THREE terms in the sequence.

• Continue the pattern to find the next THREE terms

• The pattern is +0.2

You can also write an algebraic expression to represent the relationship between any term in a sequence and its position in the sequence. In this case, if n represents the position in the sequence, the value of the term is 2n.
