Continuing sequences

How do I continue a given sequence? 

• You can work out the first differences to see if there is a pattern

  • The first differences are the values the sequence changes by each time

• For example

  • 

    • The first differences are all +3

    • The next term is 13 + 3 = 16

  • 

    • The first differences are all -5

    • The next term is -9 – 5 = -14
