Arithmetic Sequences

Sample Arithmetic Sequences questions

A few of the 70 questions, from easier to harder. Choose your exam board and tier to practise them, with every answer marked.

1. Question 12 marksGrade 1-2
   Write down the next number in this sequence: 8, 10, 12, ...
   Show the worked solution

   Each term is 2 more than the term before, so the next term is: M1

   $12 + 2 = 14$ A1
2. Question 22 marksGrade 1-2
   The number of leaves on a plant, counted each day: 4 leaves, 9 leaves, 14 leaves, ... Write down the next number in the sequence.
   Show the worked solution

What are the common mistakes in Arithmetic Sequences?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

• Drops or flips the sign of a negative common difference/ratio in a decreasing sequence

  Added 6 instead of subtracting it, treating a decreasing sequence as increasing

• Miscounts which position number a term corresponds to (e.g. treats the first given term as position 0, or the answer position as one more/less than intended)

  Applied the term-to-term rule only once instead of 2 times

• Calculates only the coefficient-times-position part of a linear sequence formula, forgetting to add the constant term

  Calculates 15n only and forgets to add the 20, giving 15, 30, 45 instead of 35, 50, 65.
