![]() They visualised the picture and saw it had yellow squares, then red rows increasing in twos and then 3 blue added each time. Students removed 1,4, 9, 16, 25 and were left with 5, 7, 9, 11, 15, they easily found 2n+3 and so managed to get the nth term. ![]() We did move onto a numerical sequence without images: This task belongs to a series of three tasks that presents students with a sequence of tile figures with the property that the n-th figure in the sequence has f. 0:00 / 6:56 Quadratic Sequences The Basics Patty Hill 2.77K subscribers Subscribe Share Save 205K views 9 years ago Archive: Kealing Algebra 1 (2013-14) This is a lesson for those 'other'. They said they really enjoyed it, they liked how they could draw or write the next term in the sequence and some recognised the quadratic part and then once you subtracted that if what remained was a constant number or a linear sequence you could finished the nth term. I used the above resources with year 8 today. I hope this will help students notice patterns and they are able to make generalisations. The next term could be an image or a number. Students could use the colours to help them see the blue is a constant addition and the red being linear. So i thought it would be a good to use some visual representations. When it came to the quadratic sequences they noticed that the second difference between each term was the same and they recognised the sequence 1, 4, 9, 16, … How do I find the nth term of a quadratic sequence Work out the sequences of first and second differences a the second difference 2 Write out the. We spent some time on linear sequences and there were patterns and they noticed how the patterns always increased by the same amount each time. ![]() ![]() A real variety of different sequences linear, quadratics, Geometric, Fibonacci etc. I had a look some sequences with year 8 today. ![]()
