The cards Question What is an arithmetic (or linear) sequence? Tap to flip Answer A sequence where the difference between successive terms is constant. Question How can an arithmetic sequence be identified? Tap to flip Answer Through a common difference between consecutive terms. Question What does the formula for the nth term of a sequence let you do? Tap to flip Answer Generate any term in the sequence from its position. Question When checking whether a sequence is arithmetic, which terms should you check? Tap to flip Answer All the terms given, not just the first few. Question What form does the nth term of an arithmetic sequence take? Tap to flip Answer d(n − 1) + a Question In the nth term d(n − 1) + a, what does a stand for? Tap to flip Answer The first term of the sequence. Question In the nth term d(n − 1) + a, what does d stand for? Tap to flip Answer The common difference between any two consecutive terms. Question The sequence 4, 9, 14, 19, ... can be seen as which times table shifted down 1? Tap to flip Answer The 5 times table. Question What is a geometric sequence? Tap to flip Answer A sequence with a constant multiplicative relationship between successive terms. Question In a geometric sequence, what is the common ratio? Tap to flip Answer The constant multiplier between successive terms. Question A geometric sequence has a common multiplier instead of what? Tap to flip Answer A common difference. Question Does a geometric sequence have a first term? Tap to flip Answer Yes, there is still a first term. Question How do you find the common ratio of a sequence? Tap to flip Answer Divide each term by the term before it; if the results are all the same, that is the common ratio. Question If a sequence has a common ratio, what type of sequence is it? Tap to flip Answer Geometric. Question What kind of terms is each geometric sequence made up of? Tap to flip Answer Discrete terms. Question If a geometric sequence's graph is drawn as a continuous line, is the sequence continuous? Tap to flip Answer No. The graph is continuous but the sequence is not. Question How are square number sequences formed? Tap to flip Answer By squaring the position within the sequence. Question How are cube number sequences formed? Tap to flip Answer By cubing the position within the sequence. Question How are triangular number sequences formed? Tap to flip Answer By increasing the difference by one between each consecutive term. Question What is a triangular number? Tap to flip Answer A number that can be represented by a pattern of dots arranged into an equilateral triangle. Question For a triangular number, what does the term number tell you? Tap to flip Answer The number of dots in a side of the triangle. Question What is a numerical sequence? Tap to flip Answer A set of numbers, often following a rule. Question What is the risk of seeing only a few terms of a sequence? Tap to flip Answer You may deduce the rule incorrectly. Question Are all sequences either arithmetic or geometric? Tap to flip Answer No. Sequences can be generated in many ways. Question Can more than one rule fit the first few terms of a sequence? Tap to flip Answer Yes, you can usually find more than one rule that fits. Question What can spotting a sequence make it possible to do? Tap to flip Answer Predict behaviour. Question Is a prediction from a sequence guaranteed? Tap to flip Answer No, as with all predictions, it is not a guarantee.

How this deck was checked On 2026-11-03, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
