How to check the work
Ask the learner to show or explain one idea, then try a fresh example with suitable support. Note any prompts needed; retelling alone does not show secure understanding.

How to study with Algebra — Module 6: Sequences, simultaneous equations & inequalities
This parent guide relates the page examples with a usable study routine. The listed resource is labelled Mathematics, GCSE, Year 10, Year 11, E-Learning Module. Use that setting, the learning summary and published prompts to clarify what effective work should reveal.
Prepare a focused session
Read the title and learning focus together. Ask the learner to anticipate the ideas, language or strategy they may need. Scan each sample and spot action words, amounts, signals, constraints or new terms. Agree a focused time window, reduce diversions and prepare useful equipment such as paper, pencil, ruler, coloured pens, calculator, headphones or a device. Encourage an independent first attempt so the response shows secure understanding and gaps. A short pause often supports recall better than an same-session answer.
Make thinking shown
Invite the learner to restate the task in their own words. They can underline essential information, divide a extended problem into individual steps, sketch a diagram, sort evidence, compose a sentence or describe a planned method. Ask why their method fits and whether another strategy could work. When movement stops, give a graduated hint: repeat the goal, point towards a related example, reduce the choice, then show only the next step. Return control directly afterwards. Spoken reasoning highlights confusions and practises accurate subject language.
Check accuracy and understanding
Compare the attempt with shown answer guidance after honest effort. Inspect more than the final response: review the method, explanation, units, evidence, sequence, spelling or presentation where related. Ask the learner to locate the first point where their reasoning changed course. Complete corrections actively in a different colour or separate space, followed by a short note of the change. For a correct answer, seek support and one independent check. This separates secure ideas from guessing while strengthening accuracy, reflection and careful working habits.
Consolidate and extend
Finish with retrieval from memory. Cover the example and ask for the central idea, process or fact again. Create one small adaptation by changing a value, condition, example, viewpoint or level of support while keeping the learning focus. Invite the learner to write a similar question and supply checking guidance. Record one success and one specific next step, perhaps reviewing terminology, practising a calculation, adding evidence or improving clarity. Recheck that target again in the week because spaced review gives clearer information than same-session repetition.
The interactive player, downloadable file and make answer material retain their existing access controls. The guide supports preparation, discussion and review.
Sample questions and answers
Try five questions from this exact activity. Review each authored answer and explanation, then note which ideas need another look. Compare the options and explain why the answer fits. Say the reasoning aloud or write a short justification before opening the interactive player to complete the activity and save progress.
What is the next term of 3, 7, 11, 15, …?
- 18
- 19
- 20
- 22
Sample answer: 19
Explanation: The sequence goes up by 4 each time: 15 + 4 = 19.
Find the nth term of 2, 4, 6, 8, …
- n + 2
- 2n
- 2n + 2
- n²
Sample answer: 2n
Explanation: It is the 2 times table, so the nth term is 2n.
Find the nth term of 3, 5, 7, 9, …
- 2n
- 2n + 1
- n + 2
- 2n − 1
Sample answer: 2n + 1
Explanation: It goes up by 2 (so 2n) and starts one above: 2n + 1.
Find the nth term of 5, 8, 11, 14, …
- 3n + 2
- 3n
- 3n + 5
- 5n + 3
Sample answer: 3n + 2
Explanation: Common difference 3 gives 3n; adjust to fit: 3n + 2.
Find the nth term of 10, 8, 6, 4, …
- 2n + 10
- 12 − 2n
- 10 − 2n
- −2n
Sample answer: 12 − 2n
Explanation: It falls by 2 (so −2n) and fits as 12 − 2n.
