Quadratic sequences gcse questions

Here we will learn about the nth term of a quadratic sequence, including generating a quadratic sequence, finding the nth term of a quadratic sequence and applying this to real life problems, quadratic sequences gcse questions. This is because when you substitute the values of 1, 2, 3, 4, and 5 into the nth term, we get the first 5 square numbers. We can therefore use this sequence as a framework when trying to find the nth term of a quadratic flyingjizz.

Here we will learn about quadratic sequences including how to recognise, use and find the nth term of a quadratic sequence. The difference between each term in a quadratic sequence is not equal, but the second difference between each term in a quadratic sequence is equal. Includes reasoning and applied questions. Quadratic sequences is part of our series of lessons to support revision on sequences. You may find it helpful to start with the main sequences lesson for a summary of what to expect, or use the step by step guides below for further detail on individual topics. Other lessons in this series include:. The second difference is equal to 2 so,.

Supercharge your learning. Step 1: Find the difference between each term, and find the second differences i. To do this, we will first find the differences between the terms in the sequence. However, if we then look at the differences between those differences , we see the second differences are the same. We will first find the differences between the terms in the sequence. To find the value of a we find the second difference, which is 6 , and divide this by 2. Subscript notation can be used to denote position to term and term to term rules. Gold Standard Education. Find the position of this term in the sequence. A term in this sequence is

The second difference is the term to term rule between the first difference. The first difference is equal to 1 so.

We can therefore use this sequence as a framework when trying to find the nth term of a quadratic sequence. Let us now reverse the question previously and use the first 5 terms in the sequence 3, 8, 15, 24, 35 to find the nth term of the sequence. So we have the sequence: 3, 8, 15, 24, The second difference is the term to term rule between the first difference. For our sequence above we have:. So how do we get from the numbers: 1, 4, 9, 16, 25 to the terms in the sequence 3, 8, 14, 24, 35? So now we have a new sequence of numbers: 2, 4, 6, 8, We can use our knowledge of finding the nth term of an arithmetic sequence to work out the nth term to be 2n.
