Sample questions

  • Enter the missing number: a, b, __, c.
  • The numbers are consecutive: a, b, c. Which number comes next?
  • The sequence begins a, b, __, c. Which number is hidden?
  • Which rule fits the sequence a, b, c?
  • Complete the sequence: a, b, __, c.

Number sequences and missing numbers

A number sequence follows a rule. Numbers may increase or decrease by one, two or another constant step. Find the rule by comparing several pairs of neighbouring terms.

Finding a missing term

Read the complete sequence and check how each next number changes. Apply the same operation to the number before the blank, then verify it against the number after the blank. Identify both the direction and the size of the step.
